Docs/admin-guide/mm/damon/lru_sort: warn commit_inputs vs param updates race
DAMON_LRU_SORT handles commit_inputs request inside kdamond thread,
reading the module parameters. If the user updates the module
parameters while the kdamond thread is reading those, races can happen.
To avoid this, the commit_inputs parameter shows whether it is still in
the progress, assuming users wouldn't update parameters in the middle of
the work. Some users might ignore that. Add a warning about the
behavior.
The issue was discovered in [1] by sashiko.

Docs/admin-guide/mm/damon/reclaim: warn commit_inputs vs param updates race
Patch series "Docs/admin-guide/mm/damon: warn commit_inputs vs other
params race".
Writing 'Y' to the commit_inputs parameter of DAMON_RECLAIM and
DAMON_LRU_SORT, and writing other parameters before the commit_inputs
request is completely processed can cause race conditions. While the
consequence can be bad, the documentation is not clearly describing that.
Add clear warnings.
The issue was discovered [1,2] by sashiko.

kho: rename fdt parameter to blob in kho_add/remove_subtree()
Since kho_add_subtree() now accepts arbitrary data blobs (not just FDTs), rename the parameter from 'fdt' to 'blob' to better reflect its purpose. Apply the same rename to kho_remove_subtree() for consistency. Also rename kho_debugfs_fdt_add() and kho_debugfs_fdt_remove() to kho_debugfs_blob_add() and kho_debugfs_blob_remove() respectively, with the same parameter rename from 'fdt' to 'blob'.

Arm:
- Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis. This uses the new infrastructure for 'remote' trace buffers that can be exposed by non-kernel entities such as firmware, and which came through the tracing tree. - Add support for GICv5 Per Processor Interrupts (PPIs), as the starting point for supporting the new GIC architecture in KVM. - Finally add support for pKVM protected guests, where pages are unmapped from the host as they are faulted into the guest and can be shared back from the guest using pKVM hypercalls. Protected guests are created using a new machine type identifier. As the elusive guestmem has not yet delivered on its promises, anonymous memory is also supported. This is only a first step towards full isolation from the host; for example, the CPU register state and DMA accesses are not yet isolated. Because this does not really yet bring fully what it promises, it is hidden behind CONFIG_ARM_PKVM_GUEST + 'kvm-arm.mode=protected', and also triggers TAINT_USER when a VM is created. Caveat emptor. - Rework the dreaded user_mem_abort() function to make it more maintainable, reducing the amount of state being exposed to the various helpers and rendering a substantial amount of state immutable. - Expand the Stage-2 page table dumper to support NV shadow page tables on a per-VM basis. - Tidy up the pKVM PSCI proxy code to be slightly less hard to follow. - Fix both SPE and TRBE in non-VHE configurations so that they do not generate spurious, out of context table walks that ultimately lead to very bad HW lockups. - A small set of patches fixing the Stage-2 MMU freeing in error cases. - Tighten-up accepted SMC immediate value to be only #0 for host SMCCC calls. - The usual cleanups and other selftest churn. LoongArch: - Use CSR_CRMD_PLV for kvm_arch_vcpu_in_kernel(). - Add DMSINTC irqchip in kernel support. RISC-V: - Fix steal time shared memory alignment checks - Fix vector context allocation leak - Fix array out-of-bounds in pmu_ctr_read() and pmu_fw_ctr_read_hi() - Fix double-free of sdata in kvm_pmu_clear_snapshot_area() - Fix integer overflow in kvm_pmu_validate_counter_mask() - Fix shift-out-of-bounds in make_xfence_request() - Fix lost write protection on huge pages during dirty logging - Split huge pages during fault handling for dirty logging - Skip CSR restore if VCPU is reloaded on the same core - Implement kvm_arch_has_default_irqchip() for KVM selftests - Factored-out ISA checks into separate sources - Added hideleg to struct kvm_vcpu_config - Factored-out VCPU config into separate sources - Support configuration of per-VM HGATP mode from KVM user space s390: - Support for ESA (31-bit) guests inside nested hypervisors. - Remove restriction on memslot alignment, which is not needed anymore with the new gmap code. - Fix LPSW/E to update the bear (which of course is the breaking event address register). x86: - Shut up various UBSAN warnings on reading module parameter before they were initialized. - Don't zero-allocate page tables that are used for splitting hugepages in the TDP MMU, as KVM is guaranteed to set all SPTEs in the page table and thus write all bytes. - As an optimization, bail early when trying to unsync 4KiB mappings if the target gfn can just be mapped with a 2MiB hugepage. x86 generic: - Copy single-chunk MMIO write values into struct kvm_vcpu (more precisely struct kvm_mmio_fragment) to fix use-after-free stack bugs where KVM would dereference stack pointer after an exit to userspace. - Clean up and comment the emulated MMIO code to try to make it easier to maintain (not necessarily "easy", but "easier"). - Move VMXON+VMXOFF and EFER.SVME toggling out of KVM (not *all* of VMX and SVM enabling) as it is needed for trusted I/O. - Advertise support for AVX512 Bit Matrix Multiply (BMM) instructions - Immediately fail the build if a required #define is missing in one of KVM's headers that is included multiple times. - Reject SET_GUEST_DEBUG with -EBUSY if there's an already injected exception, mostly to prevent syzkaller from abusing the uAPI to trigger WARNs, but also because it can help prevent userspace from unintentionally crashing the VM. - Exempt SMM from CPUID faulting on Intel, as per the spec. - Misc hardening and cleanup changes. x86 (AMD): - Fix and optimize IRQ window inhibit handling for AVIC; make it per-vCPU so that KVM doesn't prematurely re-enable AVIC if multiple vCPUs have to-be-injected IRQs. - Clean up and optimize the OSVW handling, avoiding a bug in which KVM would overwrite state when enabling virtualization on multiple CPUs in parallel. This should not be a problem because OSVW should usually be the same for all CPUs. - Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a "too large" size based purely on user input. - Clean up and harden the pinning code for KVM_MEMORY_ENCRYPT_REG_REGION. - Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as doing so for an SNP guest will crash the host due to an RMP violation page fault. - Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries are required to hold kvm->lock, and enforce it by lockdep. Fix various bugs where sev_guest() was not ensured to be stable for the whole duration of a function or ioctl. - Convert a pile of kvm->lock SEV code to guard(). - Play nicer with userspace that does not enable KVM_CAP_EXCEPTION_PAYLOAD, for which KVM needs to set CR2 and DR6 as a response to ioctls such as KVM_GET_VCPU_EVENTS (even if the payload would end up in EXITINFO2 rather than CR2, for example). Only set CR2 and DR6 when consumption of the payload is imminent, but on the other hand force delivery of the payload in all paths where userspace retrieves CR2 or DR6. - Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT instead of vmcb02->save.cr2. The value is out of sync after a save/restore or after a #PF is injected into L2. - Fix a class of nSVM bugs where some fields written by the CPU are not synchronized from vmcb02 to cached vmcb12 after VMRUN, and so are not up-to-date when saved by KVM_GET_NESTED_STATE. - Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE and KVM_SET_{S}REGS could cause vmcb02 to be incorrectly initialized after save+restore. - Add a variety of missing nSVM consistency checks. - Fix several bugs where KVM failed to correctly update VMCB fields on nested #VMEXIT. - Fix several bugs where KVM failed to correctly synthesize #UD or #GP for SVM-related instructions. - Add support for save+restore of virtualized LBRs (on SVM). - Refactor various helpers and macros to improve clarity and (hopefully) make the code easier to maintain. - Aggressively sanitize fields when copying from vmcb12, to guard against unintentionally allowing L1 to utilize yet-to-be-defined features. - Fix several bugs where KVM botched rAX legality checks when emulating SVM instructions. There are remaining issues in that KVM doesn't handle size prefix overrides for 64-bit guests. - Fail emulation of VMRUN/VMLOAD/VMSAVE if mapping vmcb12 fails instead of somewhat arbitrarily synthesizing #GP (i.e. don't double down on AMD's architectural but sketchy behavior of generating #GP for "unsupported" addresses). - Cache all used vmcb12 fields to further harden against TOCTOU bugs. x86 (Intel): - Drop obsolete branch hint prefixes from the VMX instruction macros. - Use ASM_INPUT_RM() in __vmcs_writel() to coerce clang into using a register input when appropriate. - Code cleanups. guest_memfd: - Don't mark guest_memfd folios as accessed, as guest_memfd doesn't support reclaim, the memory is unevictable, and there is no storage to write back to. LoongArch selftests: - Add KVM PMU test cases s390 selftests: - Enable more memory selftests. x86 selftests: - Add support for Hygon CPUs in KVM selftests. - Fix a bug in the MSR test where it would get false failures on AMD/Hygon CPUs with exactly one of RDPID or RDTSCP. - Add an MADV_COLLAPSE testcase for guest_memfd as a regression test for a bug where the kernel would attempt to collapse guest_memfd folios against KVM's will. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmnftRQUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroPAzwf+NKO4Ktv+7A22ImN0SBl0nlUuulsz vTcw3+hxdRoIw83GdNS+hG5js0wrpMDnbv3t4+VliDNBSSxrBzcSWX2wpilW0Xtw qGo1MWhs2lKPy1NlaRVOwPS6j7uF3AR0TQ1iQLGMedQuCU9WpiKJxyhNXJdbLrt3 8EgFzsvtEsv+jKNRUNDf9+d0j4gZsFyIe+Brhianbw+u3/UCiUClLCdsKPc4+5ZX 08otYXytacGNIf/5Ev1vT4pHkHL0yqKXAtX7LEtaS3+0KrPuLjV4slemivzE9vf5 Evafm5AhA4wpaNMb1ZerhY3T94lsMaJpWxotjR//0Q7C9B59pCQnXCm8mg== =CcE0 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "Arm: - Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis.

- The 2 patch series "pid: make sub-init creation retryable" from Oleg
Nesterov increases the robustness of our creation of init in a new

needed. Also some documentation fixups are provided.
- The 2 patch series "selftests/fchmodat2: Error handling and general"
from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall
selftest.
- The 3 patch series "lib: polynomial: Move to math/ and clean up" from
Andy Shevchenko does as advertised.
- The 3 patch series "hung_task: Provide runtime reset interface for
hung task detector" from Aaron Tomlin gives administrators the ability
to zero out /proc/sys/kernel/hung_task_detect_count.
- The 2 patch series "tools/getdelays: use the static UAPI headers from
tools/include/uapi" from Thomas Weißschuh teaches getdelays to use the
in-kernel UAPI headers rather than the system-provided ones.
- The 5 patch series "watchdog/hardlockup: Improvements to hardlockup"
from Mayank Rungta provides several cleanups and fixups to the
hardlockup detector code and its documentation.
- The 2 patch series "lib/bch: fix undefined behavior from signed
left-shifts" from Josh Law provides a couple of small/theoretical fixes
in the bch code.
- The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()"
from Junrui Luo does what is claims.
- The 27 patch series "cleanup the RAID5 XOR library" from Christoph
Hellwig is a quite far-reaching cleanup to this code. I can't do better
than to quote Christoph:
The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography and
not using the crypto API, with the generic implementations sitting in
include/asm-generic and the arch implementations sitting in an asm/
header in theory. The latter doesn't work for many cases, so
architectures often build the code directly into the core kernel, or
create another module for the architecture code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric Biggers
has done for the CRC and crypto libraries later. After that it
changes to better calling conventions that allow for smarter
architecture implementations (although none is contained here yet),
and uses static_call to avoid indirection function call overhead.
- The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
workarounds" from Kuan-Wei Chiu cleans up this library code by removing
a hacky thing which was added for UBIFS, which UBIFS doesn't actually
need.
- The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
for the now-fixed bugs and fixes a leak in the test itself.
- The 3 patch series "kdump: Enable LUKS-encrypted dump target support
in ARM64 and PowerPC" from Coiby Xu eenables support of the

Pull non-MM updates from Andrew Morton:
- "pid: make sub-init creation retryable" (Oleg Nesterov)
Make creation of init in a new namespace more robust by clearing away
some historical cruft which is no longer needed. Also some
documentation fixups
- "selftests/fchmodat2: Error handling and general" (Mark Brown)
Fix and a cleanup for the fchmodat2() syscall selftest
- "lib: polynomial: Move to math/ and clean up" (Andy Shevchenko)
- "hung_task: Provide runtime reset interface for hung task detector"
(Aaron Tomlin)
Give administrators the ability to zero out
/proc/sys/kernel/hung_task_detect_count
- "tools/getdelays: use the static UAPI headers from
tools/include/uapi" (Thomas Weißschuh)
Teach getdelays to use the in-kernel UAPI headers rather than the
system-provided ones
- "watchdog/hardlockup: Improvements to hardlockup" (Mayank Rungta)
Several cleanups and fixups to the hardlockup detector code and its
documentation
- "lib/bch: fix undefined behavior from signed left-shifts" (Josh Law)
A couple of small/theoretical fixes in the bch code
- "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo)
- "cleanup the RAID5 XOR library" (Christoph Hellwig)
A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:
"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"
- "lib/list_sort: Clean up list_sort() scheduling workarounds"
(Kuan-Wei Chiu)
Clean up this library code by removing a hacky thing which was added
for UBIFS, which UBIFS doesn't actually need
- "Fix bugs in extract_iter_to_sg()" (Christian Ehrhardt)
Fix a few bugs in the scatterlist code, add in-kernel tests for the
now-fixed bugs and fix a leak in the test itself
- "kdump: Enable LUKS-encrypted dump target support in ARM64 and
PowerPC" (Coiby Xu)
Enable support of the LUKS-encrypted device dump target on arm64 and

Networking changes for 7.1.
Core & protocols
----------------
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP.
- Number of code moves to help the compiler with inlining.
Avoid output arguments for returning drop reason where possible.
- Rework drop handling within qdiscs to include more metadata
about the reason and dropping qdisc in the tracepoints.
- Remove the rtnl_lock use from IP Multicast Routing.
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two.
- Report TCP delayed ack timer information via socket diag.
- Add ip_local_port_step_width sysctl to allow distributing the randomly
selected ports more evenly throughout the allowed space.
- Add support for per-route tunsrc in IPv6 segment routing.
- Start work of switching sockopt handling to iov_iter.
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up.
- Support MSG_EOR in MPTCP.
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage.
- Remove UDP-Lite support (as announced in 2023).
- Remove support for building IPv6 as a module.
Remove the now unnecessary function calling indirection.
Cross-tree stuff
----------------
- Move Michael MIC code from generic crypto into wireless,
it's considered insecure but some WiFi networks still need it.
Netfilter
---------
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate.
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex.
- Add more opinionated input validation to lower security exposure.
- Make IPVS hash tables to be per-netns and resizable.
Wireless
--------
- Finished assoc frame encryption/EPPKE/802.1X-over-auth.
- Radar detection improvements.
- Add 6 GHz incumbent signal detection APIs.
- Multi-link support for FILS, probe response templates and
client probing.
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware.
Driver API
----------
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs.
- Add standard counters for reporting pause storm events
(implement in mlx5 and fbnic).
- Add configuration API for completion writeback buffering
(implement in mana).
- Support driver-initiated change of RSS context sizes.
- Support DPLL monitoring input frequency (implement in zl3073x).
- Support per-port resources in devlink (implement in mlx5).
Misc
----
- Expand the YAML spec for Netfilter.

Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.
On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.
The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.

Updates for the timer/timekeeping core:
- A rework of the hrtimer subsystem to reduce the overhead for frequently
armed timers, especially the hrtick scheduler timer.
- Better timer locality decision
- Simplification of the evaluation of the first expiry time by
keeping track of the neighbor timers in the RB-tree by providing a
RB-tree variant with neighbor links. That avoids walking the
RB-tree on removal to find the next expiry time, but even more
important allows to quickly evaluate whether a timer which is
rearmed changes the position in the RB-tree with the modified
expiry time or not. If not, the dequeue/enqueue sequence which both
can end up in rebalancing can be completely avoided.
- Deferred reprogramming of the underlying clock event device. This
optimizes for the situation where a hrtimer callback sets the need
resched bit. In that case the code attempts to defer the
re-programming of the clock event device up to the point where the
scheduler has picked the next task and has the next hrtick timer
armed. In case that there is no immediate reschedule or soft
interrupts have to be handled before reaching the reschedule point
in the interrupt entry code the clock event is reprogrammed in one
of those code paths to prevent that the timer becomes stale.
- Support for clocksource coupled clockevents
The TSC deadline timer is coupled to the TSC. The next event is
programmed in TSC time. Currently this is done by converting the
CLOCK_MONOTONIC based expiry value into a relative timeout,
converting it into TSC ticks, reading the TSC adding the delta
ticks and writing the deadline MSR.
As the timekeeping core has the conversion factors for the TSC
already, the whole back and forth conversion can be completely
avoided. The timekeeping core calculates the reverse conversion
factors from nanoseconds to TSC ticks and utilizes the base
timestamps of TSC and CLOCK_MONOTONIC which are updated once per
tick. This allows a direct conversion into the TSC deadline value
without reading the time and as a bonus keeps the deadline
conversion in sync with the TSC conversion factors, which are
updated by adjtimex() on systems with NTP/PTP enabled.
- Allow inlining of the clocksource read and clockevent write
functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.
With all those enhancements in place a hrtick enabled scheduler
provides the same performance as without hrtick. But also other hrtimer
users obviously benefit from these optimizations.
- Robustness improvements and cleanups of historical sins in the hrtimer
and timekeeping code.
- Rewrite of the clocksource watchdog.
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design, which was
made in the context of systems far smaller than today, is based on the
assumption that the to be monitored clocksource (TSC) can be trivially
compared against a known to be stable clocksource (HPET/ACPI-PM timer).
Over the years this rather naive approach turned out to have major
flaws. Long delays between the watchdog invocations can cause wrap
arounds of the reference clocksource. The access to the reference
clocksource degrades on large multi-sockets systems dure to
interconnect congestion. This has been addressed with various
heuristics which degraded the accuracy of the watchdog to the point
that it fails to detect actual TSC problems on older hardware which
exposes slow inter CPU drifts due to firmware manipulating the TSC to
hide SMI time.
The rewrite addresses this by:
- Restricting the validation against the reference clocksource to the
boot CPU which is usually closest to the legacy block which
contains the reference clocksource (HPET/ACPI-PM).
- Do a round robin validation betwen the boot CPU and the other CPUs
based only on the TSC with an algorithm similar to the TSC
synchronization code during CPU hotplug.
- Being more leniant versus remote timeouts
- The usual tiny fixes, cleanups and enhancements all over the place

Pull power management updates from Rafael Wysocki:
"Once again, cpufreq is the most active development area, mostly
because of the new feature additions and documentation updates in the
amd-pstate driver, but there are also changes in the cpufreq core
related to boost support and other assorted updates elsewhere.
Next up are power capping changes due to the major cleanup of the
Intel RAPL driver.
On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.
Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates
of the operating performance points (OPP) library, two minor updates
related to hibernation, and cpupower utility man pages updates and
cleanups.

Pull ACPI support updates from Rafael Wysocki:
"These include an update of the CMOS RTC driver and the related ACPI
and x86 code that, among other things, switches it over to using the
platform device interface for device binding on x86 instead of the PNP
device driver interface (which allows the code in question to be
simplified quite a bit), a major update of the ACPI Time and Alarm
Device (TAD) driver adding an RTC class device interface to it, and
updates of core ACPI drivers that remove some unnecessary and not
really useful code from them.
Apart from that, two drivers are converted to using the platform
driver interface for device binding instead of the ACPI driver one,
which is slated for removal, support for the Performance Limited
register is added to the ACPI CPPC library and there are some
janitorial updates of it and the related cpufreq CPPC driver, the ACPI
processor driver is fixed and cleaned up, and NVIDIA vendor CPER
record handler is added to the APEI GHES code.
Also, the interface for obtaining a CPU UID from ACPI is consolidated
across architectures and used for fixing a problem with the PCI TPH
Steering Tag on ARM64, there are two updates related to ACPICA, a
minor ACPI OS Services Layer (OSL) update, and a few assorted updates
related to ACPI tables parsing.
Specifics:
- Update maintainers information regarding ACPICA (Rafael Wysocki)

Docs/mm/damon: document min_nr_regions constraint and rationale
The current DAMON implementation requires 'min_nr_regions' to be at least 3. However, this constraint is not explicitly documented in the admin-guide documents, nor is its design rationale explained in the design document. Add a section in design.rst to explain the rationale: the virtual address space monitoring design needs to handle at least three regions to accommodate two large unmapped areas. While this is specific to 'vaddr', DAMON currently enforces it across all operation sets for consistency. Also update reclaim.rst and lru_sort.rst by adding cross-references to this constraint within their respective 'min_nr_regions' parameter description sections, ensuring users are aware of the lower bound. This change is motivated from a recent discussion [1].

zram: remove chained recompression
Chained recompression has unpredictable behavior and is not useful in practice. First, systems usually configure just one alternative recompression algorithm, which has slower compression/decompression but better compression ratio. A single alternative algorithm doesn't need chaining. Second, even with multiple recompression algorithms, chained recompression is suboptimal. If a lower priority algorithm succeeds, the page is never attempted with a higher priority algorithm, leading to worse memory savings. If a lower priority algorithm fails, the page is still attempted with a higher priority algorithm, wasting resources on the failed lower priority attempt. In either case, the system would be better off targeting a specific priority directly. Chained recompression also significantly complicates the code. Remove it.

Dynamic energy performance preference changes the EPP profile based on
whether the machine is running on AC or DC power.
A notification chain from the power supply core is used to adjust EPP
values on plug in or plug out events.
When enabled, the driver exposes a sysfs toggle for dynamic EPP, blocks
manual writes to energy_performance_preference while it "owns" the EPP
updates.
For non-server systems:
* the default EPP for AC mode is `performance`.
* the default EPP for DC mode is `balance_performance`.
For server systems dynamic EPP is mostly a no-op.

zloop: add max_open_zones option
Introduce the new max_open_zones option to allow specifying a limit on the maximum number of open zones of a zloop device. This change allows creating a zloop device that can more closely mimick the characteristics of a physical SMR drive. When set to a non zero value, only up to max_open_zones zones can be in the implicit open (BLK_ZONE_COND_IMP_OPEN) and explicit open (BLK_ZONE_COND_EXP_OPEN) conditions at any time. The transition to the implicit open condition of a zone on a write operation can result in an implicit close of an already implicitly open zone. This is handled in the function zloop_do_open_zone(). This function also handles transitions to the explicit open condition. Implicit close transitions are handled using an LRU ordered list of open zones which is managed using the helper functions zloop_lru_rotate_open_zone() and zloop_lru_remove_open_zone().

NFSD: Enforce timeout on layout recall and integrate lease manager fencing
When a layout conflict triggers a recall, enforcing a timeout is necessary to prevent excessive nfsd threads from being blocked in __break_lease ensuring the server continues servicing incoming requests efficiently. This patch introduces a new function to lease_manager_operations: lm_breaker_timedout: Invoked when a lease recall times out and is about to be disposed of. This function enables the lease manager to inform the caller whether the file_lease should remain on the flc_list or be disposed of. For the NFSD lease manager, this function now handles layout recall timeouts. If the layout type supports fencing and the client has not been fenced, a fence operation is triggered to prevent the client from accessing the block device. While the fencing operation is in progress, the conflicting file_lease remains on the flc_list until fencing is complete. This guarantees that no other clients can access the file, and the client with exclusive access is properly blocked before disposal.

doc: watchdog: clarify hardlockup detection timing
The current documentation implies that a hardlockup is strictly defined as looping for "more than 10 seconds." However, the detection mechanism is periodic (based on `watchdog_thresh`), meaning detection time varies significantly depending on when the lockup occurs relative to the NMI perf event. Update the definition to remove the strict "more than 10 seconds" constraint in the introduction and defer details to the Implementation section. Additionally, add a "Detection Overhead" section illustrating the Best Case (~6s) and Worst Case (~20s) detection scenarios to provide administrators with a clearer understanding of the watchdog's latency.

hung_task: enable runtime reset of hung_task_detect_count
Currently, the hung_task_detect_count sysctl provides a cumulative count
of hung tasks since boot. In long-running, high-availability
environments, this counter may lose its utility if it cannot be reset once
an incident has been resolved. Furthermore, the previous implementation
relied upon implicit ordering, which could not strictly guarantee that
diagnostic metadata published by one CPU was visible to the panic logic on
another.
This patch introduces the capability to reset the detection count by
writing "0" to the hung_task_detect_count sysctl. The proc_handler logic
has been updated to validate this input and atomically reset the counter.
The synchronisation of sysctl_hung_task_detect_count relies upon a
transactional model to ensure the integrity of the detection counter
against concurrent resets from userspace. The application of
atomic_long_read_acquire() and atomic_long_cmpxchg_release() is correct
and provides the following guarantees:
1. Prevention of Load-Store Reordering via Acquire Semantics By
utilising atomic_long_read_acquire() to snapshot the counter
before initiating the task traversal, we establish a strict
memory barrier. This prevents the compiler or hardware from
reordering the initial load to a point later in the scan. Without
this "acquire" barrier, a delayed load could potentially read a
"0" value resulting from a userspace reset that occurred
mid-scan. This would lead to the subsequent cmpxchg succeeding
erroneously, thereby overwriting the user's reset with stale
increment data.
2. Atomicity of the "Commit" Phase via Release Semantics The
atomic_long_cmpxchg_release() serves as the transaction's commit
point. The "release" barrier ensures that all diagnostic
recordings and task-state observations made during the scan are
globally visible before the counter is incremented.
3. Race Condition Resolution This pairing effectively detects any
"out-of-band" reset of the counter. If
sysctl_hung_task_detect_count is modified via the procfs
interface during the scan, the final cmpxchg will detect the
discrepancy between the current value and the "acquire" snapshot.
Consequently, the update will fail, ensuring that a reset command
from the administrator is prioritised over a scan that may have
been invalidated by that very reset.

clocksource: Rewrite watchdog code completely
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design, which was
made in the context of systems far smaller than today, is based on the
assumption that the to be monitored clocksource (TSC) can be trivially
compared against a known to be stable clocksource (HPET/ACPI-PM timer).
Over the years it turned out that this approach has major flaws:
- Long delays between watchdog invocations can result in wrap arounds
of the reference clocksource
- Scalability of the reference clocksource readout can degrade on large
multi-socket systems due to interconnect congestion
This was addressed with various heuristics which degraded the accuracy of
the watchdog to the point that it fails to detect actual TSC problems on
older hardware which exposes slow inter CPU drifts due to firmware
manipulating the TSC to hide SMI time.
To address this and bring back sanity to the watchdog, rewrite the code
completely with a different approach:
1) Restrict the validation against a reference clocksource to the boot
CPU, which is usually the CPU/Socket closest to the legacy block which
contains the reference source (HPET/ACPI-PM timer). Validate that the
reference readout is within a bound latency so that the actual
comparison against the TSC stays within 500ppm as long as the clocks
are stable.
2) Compare the TSCs of the other CPUs in a round robin fashion against
the boot CPU in the same way the TSC synchronization on CPU hotplug
works. This still can suffer from delayed reaction of the remote CPU
to the SMP function call and the latency of the control variable cache
line. But this latency is not affecting correctness. It only affects
the accuracy. With low contention the readout latency is in the low
nanoseconds range, which detects even slight skews between CPUs. Under
high contention this becomes obviously less accurate, but still
detects slow skews reliably as it solely relies on subsequent readouts
being monotonically increasing. It just can take slightly longer to
detect the issue.
3) Rewrite the watchdog test so it tests the various mechanisms one by
one and validating the result against the expectation.

x86/vsyscall: Disable LASS if vsyscall mode is set to EMULATE
The EMULATE mode of vsyscall maps the vsyscall page with a high kernel
address directly into user address space. Reading the vsyscall page in
EMULATE mode would cause LASS to trigger a #GP.
Fixing the LASS violation in EMULATE mode would require complex
instruction decoding because the resulting #GP does include the
necessary error information, and the vsyscall address is not
readily available in the RIP.
The EMULATE mode has been deprecated since 2022 and can only be enabled
using the command line parameter vsyscall=emulate. See commit

ima: remove buggy support for asynchronous hashes
IMA computes hashes using the crypto_shash or crypto_ahash API. The latter is used only when ima.ahash_minsize is set on the command line, and its purpose is ostensibly to make the hash computation faster. However, going off the CPU to a crypto engine and back again is actually quite slow, especially compared with the acceleration that is built into modern CPUs and the kernel now enables by default for most algorithms. Typical performance results for SHA-256 on a modern platform can be found at https://lore.kernel.org/linux-crypto/20250615184638.GA1480@sol/ Partly for this reason, several other kernel subsystems have already dropped support for the crypto_ahash API. The other problem with crypto_ahash is that bugs are also common, not just in the underlying drivers, but also in the code using it, since it is very difficult to use correctly. Just from a quick review, here are some of the bugs I noticed in IMA's ahash code: - [Use after free] ima_alloc_atfm() isn't thread-safe and can trigger a use-after-free if multiple threads try to initialize the global ima_ahash_tfm at the same time. - [Deadlock] If only one buffer is allocated and there is an error reading from the file, then ahash_wait() is executed twice, causing a deadlock in wait_for_completion(). - [Crash or incorrect hash computed] calc_buffer_ahash_atfm() is sometimes passed stack buffers which can be vmalloc addresses, but it puts them in a scatterlist assuming they are linear addresses. This causes the hashing to be done on the wrong physical address. - [Truncation to 32-bit length] ima_alloc_pages() incorrectly assumes an loff_t value fits in an unsigned long. calc_buffer_ahash_atfm() incorrectly assumes that a loff_t value fits in an unsigned int. So, not exactly a great track record so far, even disregarding driver bugs which are an even larger problem. Fortunately, in practice it's unlikely that many users are actually setting the ima.ahash_minsize kernel command-line parameter which enables this code. However, given that this code is almost certainly no longer useful (if it ever was), let's just remove it instead of attempting to fix all these issues.

Add a new quirk USB_QUIRK_FORCE_ONE_CONFIG to handle such devices. When this quirk is set, assume the device has 1 configuration instead of failing with -EINVAL. This quirk is applied to the device with VID:PID 5131:2007 which exhibits this behavior.

zram: rename writeback_compressed device attr
Rename writeback_compressed attr to compressed_writeback to avoid possible
confusion and have more natural naming. writeback_compressed may look
like an alternative version of writeback while in fact
writeback_compressed only sets a writeback property. Make this
distinction more clear with a new compressed_writeback name.
This updates a feature which is new in 7.0-rcX.

ACPI: OSL: Poweroff when encountering a fatal ACPI error
The ACPI spec states that the operating system should respond to a fatal ACPI error by "performing a controlled OS shutdown in a timely fashion". Comply with the ACPI specification by powering off the system when ACPICA signals a fatal ACPI error. Users can still disable this behavior by using the acpi.poweroff_on_fatal kernel option to work around firmware bugs.

platform/x86: uniwill-laptop: Rename FN lock and super key lock attrs
It turns out that both sysfs attributes actually directly control
the FN lock status/super key enable status, rather than the
triggering of the associated events. This behavior was first observed
on a Tuxedo notebook and was belived to be a hardware quirk.
However, it seems that i simply misunderstood the manual of the
OEM software for Intel NUC devices. The correct behavior is:
- fn_lock_toggle_enable enables/disables FN lock mode
- super_key_toggle_enable enables/disables the super key
Rename both sysfs attributes to avoid confusing users.

More power management updates for 7.0-rc1
- Fix the handling of package-scope MSRs in the intel_rapl power
capping driver when called from the PMU subsystem and make it add all
package CPUs to the PMU cpumask to allow tools to read RAPL events
from any CPU in the package (Kuppuswamy Satharayananyan)
- Rework the invalid version check in the intel_rapl_tpmi power capping
driver to account for the fact that on partitioned systems, multiple
TPMI instances may exist per package, but RAPL registers are only
valid on one instance (Kuppuswamy Satharayananyan)
- Describe the new intel_idle.table command line option in the
admin-guide intel_idle documentation (Artem Bityutskiy)
- Fix a crash in the ladder cpuidle governor on systems with only one
(polling) idle state available by making the cpuidle core bypass the
governor in those cases and adjust the other existing governors to
that change (Aboorva Devarajan, Christian Loehle)
- Update kerneldoc comments for wake IRQ management functions that
have not been matching the code (Wang Jiayue)

Loongarch:
- Add more CPUCFG mask bits. - Improve feature detection. - Add lazy load support for FPU and binary translation (LBT) register state. - Fix return value for memory reads from and writes to in-kernel devices. - Add support for detecting preemption from within a guest. - Add KVM steal time test case to tools/selftests. ARM: - Add support for FEAT_IDST, allowing ID registers that are not implemented to be reported as a normal trap rather than as an UNDEF exception. - Add sanitisation of the VTCR_EL2 register, fixing a number of UXN/PXN/XN bugs in the process. - Full handling of RESx bits, instead of only RES0, and resulting in SCTLR_EL2 being added to the list of sanitised registers. - More pKVM fixes for features that are not supposed to be exposed to guests. - Make sure that MTE being disabled on the pKVM host doesn't give it the ability to attack the hypervisor. - Allow pKVM's host stage-2 mappings to use the Force Write Back version of the memory attributes by using the "pass-through' encoding. - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the guest. - Preliminary work for guest GICv5 support. - A bunch of debugfs fixes, removing pointless custom iterators stored in guest data structures. - A small set of FPSIMD cleanups. - Selftest fixes addressing the incorrect alignment of page allocation. - Other assorted low-impact fixes and spelling fixes. RISC-V: - Fixes for issues discoverd by KVM API fuzzing in kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and kvm_riscv_vcpu_aia_imsic_update() - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM - Transparent huge page support for hypervisor page tables - Adjust the number of available guest irq files based on MMIO register sizes found in the device tree or the ACPI tables - Add RISC-V specific paging modes to KVM selftests - Detect paging mode at runtime for selftests s390: - Performance improvement for vSIE (aka nested virtualization) - Completely new memory management. s390 was a special snowflake that enlisted help from the architecture's page table management to build hypervisor page tables, in particular enabling sharing the last level of page tables. This however was a lot of code (~3K lines) in order to support KVM, and also blocked several features. The biggest advantages is that the page size of userspace is completely independent of the page size used by the guest: userspace can mix normal pages, THPs and hugetlbfs as it sees fit, and in fact transparent hugepages were not possible before. It's also now possible to have nested guests and guests with huge pages running on the same host. - Maintainership change for s390 vfio-pci - Small quality of life improvement for protected guests x86: - Add support for giving the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allowing direct access to data MSRs and PMCs (restricted by the vPMU model). KVM still intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. This is more accurate, since it has no risk of contention and thus dropped events, and also has significantly less overhead. For more information, see the commit message for merge commit |

Networking changes for 7.0
Core & protocols
----------------
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls for
small helper and stack canary overhead in the fast-path. This
generates better and faster code with very small or no text size
increases, as in many cases the call generated more code than the
actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage by
up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the RX
path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without the
HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified, aligning
IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the rate
shaper of sch_cake across multiple CPUs, while still enforcing a
single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations that
are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information, saving
cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most protocols,
avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies between
the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes back
online.
Driver API
----------
- Support for switching the working mode (automatic vs manual) of a DPLL
device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties, to
generalize polarity inversion requirements for differential signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers
--------------
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet controller.

Pull networking updates from Paolo Abeni:
"Core & protocols:
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers:
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().
- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.

- add TSO support for UDP over GRE over VLAN
- add flow counters support for hardware steering (HWS) rules
- use a static memory area to store headers for H/W GRO,
leading to 12% RX tput improvement
- Intel (100G, ice, idpf):
- ice: reorganizes layout of Tx and Rx rings for cacheline
locality and utilizes __cacheline_group* macros on the new
layouts
- ice: introduces Synchronous Ethernet (SyncE) support
- Meta (fbnic):
- adds debugfs for firmware mailbox and tx/rx rings vectors

Merge tag 'kvm-x86-pmu-6.20' of https://github.com/kvm-x86/linux into HEAD
KVM mediated PMU support for 6.20 Add support for mediated PMUs, where KVM gives the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allows direct access to data MSRs and PMCs (restricted by the vPMU model), but intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. To keep overall complexity reasonable, mediated PMU usage is all or nothing for a given instance of KVM (controlled via module param). The Mediated PMU is disabled default, partly to maintain backwards compatilibity for existing setup, partly because there are tradeoffs when running with a mediated PMU that may be non-starters for some use cases, e.g. the host loses the ability to profile guests with mediated PMUs, the fastpath run loop is also a blind spot, entry/exit transitions are more expensive, etc. Versus the emulated PMU, where KVM is "just another perf user", the mediated PMU delivers more accurate profiling and monitoring (no risk of contention and thus dropped events), with significantly less overhead (fewer exits and faster emulation/programming of event selectors) E.g. when running Specint-2017 on a single-socket Sapphire Rapids with 56 cores and no-SMT, and using perf from within the guest: Perf command: a. basic-sampling: perf record -F 1000 -e 6-instructions -a --overwrite b. multiplex-sampling: perf record -F 1000 -e 10-instructions -a --overwrite Guest performance overhead: --------------------------------------------------------------------------- | Test case | emulated vPMU | all passthrough | passthrough with | | | | | event filters | --------------------------------------------------------------------------- | basic-sampling | 33.62% | 4.24% | 6.21% | --------------------------------------------------------------------------- | multiplex-sampling | 79.32% | 7.34% | 10.45% | --------------------------------------------------------------------------- |

Scheduler changes for v7.0:
Scheduler Kconfig space updates:
- Further consolidate configurable preemption modes: reduce
the number of architectures that are allowed to offer
PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number
of preemption models from four to just two: 'full' and 'lazy'
on up-to-date architectures (arm64, loongarch, powerpc,
riscv, s390, x86).
None and voluntary are only available as legacy features
on platforms that don't implement lazy preemption yet,
or which don't even support preemption.
The goal is to eventually remove cond_resched() and
voluntary preemption altogether.
(Peter Zijlstra)
RSEQ based 'scheduler time slice extension' support:
This allows a thread to request a time slice extension when it
enters a critical section to avoid contention on a resource when
the thread is scheduled out inside of the critical section.
- Add fields and constants for time slice extension
- Provide static branch for time slice extensions
- Add statistics for time slice extensions
- Add prctl() to enable time slice extensions
- Implement sys_rseq_slice_yield()
- Implement syscall entry work for time slice extensions
- Implement time slice extension enforcement timer
- Reset slice extension when scheduled
- Implement rseq_grant_slice_extension()
- entry: Hook up rseq time slice extension
- selftests: Implement time slice extension test
(Thomas Gleixner)
- Allow registering RSEQ with slice extension
- Move slice_ext_nsec to debugfs
- Lower default slice extension
- selftests/rseq: Add rseq slice histogram script
(Peter Zijlstra)
Scheduler performance/scalability improvements:
- Update rq->avg_idle when a task is moved to an idle CPU,
which improves the scalability of various workloads.
(Shubhang Kaushik)
- Reorder fields in 'struct rq' for better caching
(Blake Jones)
- Fair scheduler SMP NOHZ balancing code speedups:
- Move checking for nohz cpus after time check
- Change likelyhood of nohz.nr_cpus
- Remove nohz.nr_cpus and use weight of cpumask instead
(Shrikanth Hegde)
- Avoid false sharing for sched_clock_irqtime (Wangyang Guo)
- Drop useless cpumask_empty() in find_energy_efficient_cpu()
- Simplify task_numa_find_cpu()
- Use cpumask_weight_and() in sched_balance_find_dst_group()
(Yury Norov)
DL scheduler updates:
- Add a deadline server for sched_ext tasks (by Andrea Righi and
Joel Fernandes, with fixes by Peter Zijlstra)
RT scheduler updates:
- Skip currently executing CPU in rto_next_cpu() (Chen Jinghuang)
Entry code updates and performance improvements, which is part of the
scheduler tree in this cycle due to interdependencies with the RSEQ
based time slice extension work:
- Remove unused syscall argument from syscall_trace_enter()
- Rework syscall_exit_to_user_mode_work() for architecture reuse
- Add arch_ptrace_report_syscall_entry/exit()
- Inline syscall_exit_work() and syscall_trace_enter()
(Jinjie Ruan)
Scheduler core updates:
- Rework sched_class::wakeup_preempt() and rq_modified_*()
- Avoid rq->lock bouncing in sched_balance_newidle()
- Rename rcu_dereference_check_sched_domain() =>
rcu_dereference_sched_domain()
- <linux/compiler_types.h>: Add the __signed_scalar_typeof() helper
(Peter Zijlstra)
Fair scheduler updates/refactoring:
- Fold the sched_avg update
- Change rcu_dereference_check_sched_domain() to rcu-sched
- Switch to rcu_dereference_all()
- Remove superfluous rcu_read_lock()
- Limit hrtick work
(Peter Zijlstra)
- Join two #ifdef CONFIG_FAIR_GROUP_SCHED blocks
- Clean up comments in 'struct cfs_rq'
- Separate se->vlag from se->vprot
- Rename cfs_rq::avg_load to cfs_rq::sum_weight
- Rename cfs_rq::avg_vruntime to ::sum_w_vruntime & helper functions
- Introduce and use the vruntime_cmp() and vruntime_op() wrappers
for wrapped-signed aritmetics
- Sort out 'blocked_load*' namespace noise
(Ingo Molnar)
Scheduler debugging code updates:
- Export hidden tracepoints to modules (Gabriele Monaco)
- Convert copy_from_user() + kstrtouint() to kstrtouint_from_user()
(Fushuai Wang)
- Add assertions to QUEUE_CLASS (Peter Zijlstra)
- hrtimer: Fix tracing oddity (Thomas Gleixner)
Misc fixes and cleanups:
- Re-evaluate scheduling when migrating queued tasks out of
throttled cgroups (Zicheng Qu)
- Remove task_struct->faults_disabled_mapping (Christoph Hellwig)
- Fix math notation errors in avg_vruntime comment (Zhan Xusheng)
- sched/cpufreq: Use %pe format for PTR_ERR() printing (zenghongling)

LoongArch: Add HOTPLUG_SMT implementation
For benchmarking or debugging purpose, we usually want to control SMT via boot parameter and sysfs knobs. So add HOTPLUG_SMT implementation. 1. Boot parameters: nosmt: Disable SMT, can be enabled via sysfs knobs. nosmt=force: Disable SMT, cannot be enabled via sysfs knobs. 2. Runtime sysfs controls: Write "on", "off", "forceoff" or the number of SMT threads (1, 2, ...) to /sys/devices/system/cpu/smt/control. Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

A slightly calmer cycle for docs this time around, though there is still a
fair amount going on, including:
- Some signs of life on the long-moribund Japanese translation
- Documentation on policies around the use of generative tools for patch
submissions, and a separate document intended for consumption by
generative tools.
- The completion of the move of the documentation tools to tools/docs. For
now we're leaving a /scripts/kernel-doc symlink behind to avoid breaking
scripts.
- Ongoing build-system work includes the incorporation of documentation in
Python code, better support for documenting variables, and lots of
improvements and fixes.
- Automatic linking of man-page references -- cat(1), for example -- to
the online pages in the HTML build.
...and the usual array of typo fixes and such.

Pull power management updates from Rafael Wysocki:
"By the number of commits, cpufreq is the leading party (again) and the
most visible change there is the removal of the omap-cpufreq driver
that has not been used for a long time (good riddance). There are also
quite a few changes in the cppc_cpufreq driver, mostly related to
fixing its frequency invariance engine in the case when the CPPC
registers used by it are not in PCC. In addition to that, support for
AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev
list is updated for some platforms. The remaining cpufreq changes are
assorted fixes and cleanups.
Next up is cpuidle and the changes there are dominated by intel_idle
driver updates, mostly related to the new command line facility
allowing users to adjust the list of C-states used by the driver.
There are also a few updates of cpuidle governors, including two menu
governor fixes and some refinements of the teo governor, and a
MAINTAINERS update adding Christian Loehle as a cpuidle reviewer.
[Thanks for stepping up Christian!]
The most significant update related to system suspend and hibernation
is the one to stop freezing the PM runtime workqueue during system PM
transitions which allows some deadlocks to be avoided. There is also a
fix for possible concurrent bit field updates in the core device
suspend code and a few other minor fixes.
Apart from the above, several drivers are updated to discard the
return value of pm_runtime_put() which is going to be converted to a
void function as soon as everybody stops using its return value, PL4
support for Ice Lake is added to the Intel RAPL power capping driver,
and there are assorted cleanups, documentation fixes, and some
cpupower utility improvements.
Specifics:
- Remove the unused omap-cpufreq driver (Andreas Kemnade)
- Optimize error handling code in cpufreq_boost_trigger_state() and

The linuxrc initrd path was deprecated in 2020 and this series completes its removal. If we see real-life regressions we'll revert. The core change removes handle_initrd() and init_linuxrc() — the entire flow that ran /linuxrc from an initrd, pivoted roots, and handed off to the real root filesystem. With that gone, initrd_load() becomes void (no longer short-circuits prepare_namespace()), rd_load_image() is simplified to always load /initrd.image instead of taking a path, and rd_load_disk() is deleted. The /proc/sys/kernel/real-root-dev sysctl and its backing variable are removed since they only existed for linuxrc to communicate the real root device back to the kernel. The no-op load_ramdisk= and prompt_ramdisk= parameters are dropped, and noinitrd and ramdisk_start= gain deprecation warnings. Initramfs is entirely unaffected.

RCU changes for v7.0
RCU Tasks Trace:
Re-implement RCU tasks trace in term of SRCU-fast, not only more than 500 lines
of code are saved because of the reimplementation, a new set of API,
rcu_read_{,un}lock_tasks_trace(), becomes possible as well. Compared to the
previous rcu_read_{,un}lock_trace(), the new API avoid the task_struct accesses
thanks to the SRCU-fast semantics. As a result, the old
rcu_read{,un}lock_trace() API is now deprecated.
RCU Torture Test:
- Multiple improvements on kvm-series.sh (parallel run and progress showing
metrics)
- Add context checks to rcu_torture_timer().
- Make config2csv.sh properly handle comments in .boot files.
- Include commit discription in testid.txt.
Miscellaneous RCU changes:
- Reduce synchronize_rcu() latency by reporting GP kthread's CPU QS early.
- Use suitable gfp_flags for the init_srcu_struct_nodes().
- Fix rcu_read_unlock() deadloop due to softirq.
- Correctly compute probability to invoke ->exp_current() in rcutorture.
- Make expedited RCU CPU stall warnings detect stall-end races.
RCU nocb:
- Remove unnecessary WakeOvfIsDeferred wake path and callback overload
handling.
- Extract nocb_defer_wakeup_cancel() helper.

workqueue: add time-based panic for stalls
Add a new module parameter 'panic_on_stall_time' that triggers a panic when a workqueue stall persists for longer than the specified duration in seconds. Unlike 'panic_on_stall' which counts accumulated stall events, this parameter triggers based on the duration of a single continuous stall. This is useful for catching truly stuck workqueues rather than accumulating transient stalls. Usage: workqueue.panic_on_stall_time=120 This would panic if any workqueue pool has been stalled for 120 seconds or more. The stall duration is measured from the workqueue last progress (poll_ts) which accounts for legitimate system stalls.

nvme: add support for dynamic quirk configuration via module parameter
Introduce support for enabling or disabling specific NVMe quirks at module load time through the `quirks` module parameter. This mechanism allows users to apply known quirks dynamically based on the device's PCI vendor and device IDs, without requiring to add hardcoded entries in the driver and recompiling the kernel. While the generic PCI new_id sysfs interface exists for dynamic configuration, it is insufficient for scenarios where the system fails to boot (for example, this has been reported to happen because of the bogus_nid quirk). The new_id attribute is writable only after the system has booted and sysfs is mounted. The `quirks` parameter accepts a list of quirk specifications separated by a '-' character in the following format: <VID>:<DID>:<quirk_names>[-<VID>:<DID>:<quirk_names>-..] Each quirk is represented by its name and can be prefixed with `^` to indicate that the quirk should be disabled; quirk names are separated by a ',' character. Example: enable BOGUS_NID and BROKEN_MSI, disable DEALLOCATE_ZEROES: $ modprobe nvme quirks=7170:2210:bogus_nid,broken_msi,^deallocate_zeroes Tested-by: Daniel Wagner <dwagner@suse.de> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Maurizio Lombardi <mlombard@redhat.com> Signed-off-by: Daniel Wagner <dwagner@suse.de> Signed-off-by: Keith Busch <kbusch@kernel.org> |

bootconfig: Terminate value search if it hits a newline
Terminate the value search for a key if it hits a newline and make
the value empty.
When we pass a bootconfig with an empty value terminated by the
newline, like below::
foo =
bar = value
Current bootconfig interprets it as a single entry::
foo = "bar = value";
The Documentation/admin-guide/bootconfig.rst defines the value
itself is terminated by newline:
The value has to be terminated by semi-colon (``;``) or newline (``\n``).
but it does not define when the value search is terminated.
This changes the behavior to be more line-oriented, so that it is
clearer in how it works.
- The value search of key-value pair will be terminated by a comment
or newline.
- The value search of an array will continue beyond comments and
newlines.
Thus, with this update, the above example is interpreted as::
foo = "";
bar = "value";
And the below example will cause a syntax error because "bar" is expected
as a key but it has ','.
foo =
bar, buz
According to this change, one wrong example config is updated.

workqueue: add CONFIG_BOOTPARAM_WQ_STALL_PANIC option
Add a kernel config option to set the default value of workqueue.panic_on_stall, similar to CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC, CONFIG_BOOTPARAM_HARDLOCKUP_PANIC and CONFIG_BOOTPARAM_HUNG_TASK_PANIC. This allows setting the number of workqueue stalls before triggering a kernel panic at build time, which is useful for high-availability systems that need consistent panic-on-stall, in other words, those servers which run with CONFIG_BOOTPARAM_*_PANIC=y already. The default remains 0 (disabled). Setting it to 1 will panic on the first stall, and higher values will panic after that many stall warnings. The value can still be overridden at runtime via the workqueue.panic_on_stall boot parameter or sysfs. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org> |

panic: add panic_force_cpu= parameter to redirect panic to a specific CPU
Some platforms require panic handling to execute on a specific CPU for crash dump to work reliably. This can be due to firmware limitations, interrupt routing constraints, or platform-specific requirements where only a single CPU is able to safely enter the crash kernel. Add the panic_force_cpu= kernel command-line parameter to redirect panic execution to a designated CPU. When the parameter is provided, the CPU that initially triggers panic forwards the panic context to the target CPU via IPI, which then proceeds with the normal panic and kexec flow. The IPI delivery is implemented as a weak function (panic_smp_redirect_cpu) so architectures with NMI support can override it for more reliable delivery. If the specified CPU is invalid, offline, or a panic is already in progress on another CPU, the redirection is skipped and panic continues on the current CPU.

modsign: Enable ML-DSA module signing
Allow ML-DSA module signing to be enabled. Note that OpenSSL's CMS_*() function suite does not, as of OpenSSL-3.6, support the use of CMS_NOATTR with ML-DSA, so the prohibition against using signedAttrs with module signing has to be removed. The selected digest then applies only to the algorithm used to calculate the digest stored in the messageDigest attribute. The OpenSSL development branch has patches applied that fix this[1], but it appears that that will only be available in OpenSSL-4. [1] https://github.com/openssl/openssl/pull/28923 sign-file won't set CMS_NOATTR if openssl is earlier than v4, resulting in the use of signed attributes. The ML-DSA algorithm takes the raw data to be signed without regard to what digest algorithm is specified in the CMS message. The CMS specified digest algorithm is ignored unless signedAttrs are used; in such a case, only SHA512 is permitted.

net: expand NETDEV_RSS_KEY_LEN to 256 bytes
NETDEV_RSS_KEY_LEN has been set to 52 bytes in 2014, until now.
Jakub suggested we bump the size to 128 bytes or more.
Some drivers (like idpf) were already working around the core limit.
Since this change might cause some issues in admin scripts,
bump it directly to 256 in one go.

Documentation: use a source-read extension for the index link boilerplate
The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

rseq: Implement time slice extension enforcement timer
If a time slice extension is granted and the reschedule delayed, the kernel
has to ensure that user space cannot abuse the extension and exceed the
maximum granted time.
It was suggested to implement this via the existing hrtick() timer in the
scheduler, but that turned out to be problematic for several reasons:
1) It creates a dependency on CONFIG_SCHED_HRTICK, which can be disabled
independently of CONFIG_HIGHRES_TIMERS
2) HRTICK usage in the scheduler can be runtime disabled or is only used
for certain aspects of scheduling.
3) The function is calling into the scheduler code and that might have
unexpected consequences when this is invoked due to a time slice
enforcement expiry. Especially when the task managed to clear the
grant via sched_yield(0).
It would be possible to address #2 and #3 by storing state in the
scheduler, but that is extra complexity and fragility for no value.
Implement a dedicated per CPU hrtimer instead, which is solely used for the
purpose of time slice enforcement.
The timer is armed when an extension was granted right before actually
returning to user mode in rseq_exit_to_user_mode_restart().
It is disarmed, when the task relinquishes the CPU. This is expensive as
the timer is probably the first expiring timer on the CPU, which means it
has to reprogram the hardware. But that's less expensive than going through
a full hrtimer interrupt cycle for nothing.

watchdog: softlockup: panic when lockup duration exceeds N thresholds
The softlockup_panic sysctl is currently a binary option: panic immediately or never panic on soft lockups. Panicking on any soft lockup, regardless of duration, can be overly aggressive for brief stalls that may be caused by legitimate operations. Conversely, never panicking may allow severe system hangs to persist undetected. Extend softlockup_panic to accept an integer threshold, allowing the kernel to panic only when the normalized lockup duration exceeds N watchdog threshold periods. This provides finer-grained control to distinguish between transient delays and persistent system failures. The accepted values are: - 0: Don't panic (unchanged) - 1: Panic when duration >= 1 * threshold (20s default, original behavior) - N > 1: Panic when duration >= N * threshold (e.g., 2 = 40s, 3 = 60s.) The original behavior is preserved for values 0 and 1, maintaining full backward compatibility while allowing systems to tolerate brief lockups while still catching severe, persistent hangs.

mm/block/fs: remove laptop_mode
Laptop mode was introduced to save battery, by delaying and consolidating writes and thereby maximize the time rotating hard drives wouldn't have to spin. Luckily, rotating hard drives, with their high spin-up times and power draw, are a thing of the past for battery-powered devices. Reclaim has also since changed to not write single filesystem pages anymore, and regular filesystem writeback is lumpy by design. The juice doesn't appear worth the squeeze anymore. The footprint of the feature is small, but nevertheless it's a complicating factor in mm, block, filesystems. Developers don't think about it, and it likely hasn't been tested with new reclaim and writeback changes in years. Let's sunset it. Keep the sysctl with a deprecation warning around for a few more cycles, but remove all functionality behind it.

dm-verity: add dm-verity keyring
Add a dedicated ".dm-verity" keyring for root hash signature verification, similar to the ".fs-verity" keyring used by fs-verity. By default the keyring is unused retaining the exact same old behavior. For systems that provision additional keys only intended for dm-verity images during boot, the dm_verity.keyring_unsealed=1 kernel parameter leaves the keyring open. We want to use this in systemd as a way add keys during boot that are only used for creating dm-verity devices for later mounting and nothing else. The discoverable disk image (DDI) spec at [1] heavily relies on dm-verity and we would like to expand this even more. This will allow us to do that in a fully backward compatible way. Once provisioning is complete, userspace restricts and activates it for dm-verity verification. If userspace fully seals the keyring then it gains the guarantee that no new keys can be added.

x86/acpi: Add acpi=spcr to use SPCR-provided default console
The SPCR provided console on x86 is only available as a boot console when
earlycon is provided on the kernel command line, and will not be present in
/proc/consoles.
While it's possible to retain the boot console with the keep_bootcon
parameter, that leaves the console using the less efficient 8250_early driver.
Users wanting to use the firmware suggested console (to avoid maintaining
unique serial console parameters for different server models in large fleets)
with the conventional driver have to parse the kernel log for the console
parameters and reinsert them.

docs: make kptr_restrict and hash_pointers reference each other
vsprintf.c uses a mix of the `kernel.kptr_restrict` sysctl and the `hash_pointers` boot param to control pointer hashing. But that wasn't possible to tell without looking at the source code.

net: add net.core.qdisc_max_burst
In blamed commit, I added a check against the temporary queue
built in __dev_xmit_skb(). Idea was to drop packets early,
before any spinlock was acquired.
if (unlikely(defer_count > READ_ONCE(q->limit))) {
kfree_skb_reason(skb, SKB_DROP_REASON_QDISC_DROP);
return NET_XMIT_DROP;
}
It turned out that HTB Qdisc has a zero q->limit.
HTB limits packets on a per-class basis.
Some of our tests became flaky.
Add a new sysctl : net.core.qdisc_max_burst to control
how many packets can be stored in the temporary lockless queue.
Also add a new QDISC_BURST_DROP drop reason to better diagnose
future issues.
Thanks Neal !

cgroup/cpuset: Don't invalidate sibling partitions on cpuset.cpus conflict
Currently, when setting a cpuset's cpuset.cpus to a value that conflicts with the cpuset.cpus/cpuset.cpus.exclusive of a sibling partition, the sibling's partition state becomes invalid. This is overly harsh and is probably not necessary. The cpuset.cpus.exclusive control file, if set, will override the cpuset.cpus of the same cpuset when creating a cpuset partition. So cpuset.cpus has less priority than cpuset.cpus.exclusive in setting up a partition. However, it cannot override a conflicting cpuset.cpus file in a sibling cpuset and the partition creation process will fail. This is inconsistent. That will also make using cpuset.cpus.exclusive less valuable as a tool to set up cpuset partitions as the users have to check if such a cpuset.cpus conflict exists or not. Fix these problems by making sure that once a cpuset.cpus.exclusive is set without failure, it will always be allowed to form a valid partition as long as at least one CPU can be granted from its parent irrespective of the state of the siblings' cpuset.cpus values. Of course, setting cpuset.cpus.exclusive will fail if it conflicts with the cpuset.cpus.exclusive or the cpuset.cpus.exclusive.effective value of a sibling. Partition can still be created by setting only cpuset.cpus without setting cpuset.cpus.exclusive. However, any conflicting CPUs in sibling's cpuset.cpus.exclusive.effective and cpuset.cpus.exclusive values will be removed from its cpuset.cpus.exclusive.effective as long as there is still one or more CPUs left and can be granted from its parent. This CPU stripping is currently done in rm_siblings_excl_cpus(). The new code will now try its best to enable the creation of new partitions with only cpuset.cpus set without invalidating existing ones. However it is not guaranteed that all the CPUs requested in cpuset.cpus will be used in the new partition even when all these CPUs can be granted from the parent. This is similar to the fact that cpuset.cpus.effective may not be able to include all the CPUs requested in cpuset.cpus. In this case, the parent may not able to grant all the exclusive CPUs requested in cpuset.cpus to cpuset.cpus.exclusive.effective if some of them have already been granted to other partitions earlier. With the creation of multiple sibling partitions by setting only cpuset.cpus, this does have the side effect that their exact cpuset.cpus.exclusive.effective settings will depend on the order of partition creation if there are conflicts. Due to the exclusive nature of the CPUs in a partition, it is not easy to make it fair other than the old behavior of invalidating all the conflicting partitions. For example, # echo "0-2" > A1/cpuset.cpus # echo "root" > A1/cpuset.cpus.partition # cat A1/cpuset.cpus.partition root # cat A1/cpuset.cpus.exclusive.effective 0-2 # echo "2-4" > B1/cpuset.cpus # echo "root" > B1/cpuset.cpus.partition # cat B1/cpuset.cpus.partition root # cat B1/cpuset.cpus.exclusive.effective 3-4 # cat B1/cpuset.cpus.effective 3-4 For users who want to be sure that they can get most of the CPUs they want, cpuset.cpus.exclusive should be used instead if they can set it successfully without failure. Setting cpuset.cpus.exclusive will guarantee that sibling conflicts from then onward is no longer possible. To make this change, we have to separate out the is_cpu_exclusive() check in cpus_excl_conflict() into a cgroup v1 only cpuset1_cpus_excl_conflict() helper. The cpus_allowed_validate_change() helper is now no longer needed and can be removed. Some existing tests in test_cpuset_prs.sh are updated and new ones are added to reflect the new behavior. The cgroup-v2.rst doc file is also updated the clarify what exclusive CPUs will be used when a partition is created.

x86/resctrl: Add energy/perf choices to rdt boot option
Legacy resctrl features are enumerated by X86_FEATURE_* flags. These may be overridden by quirks to disable features in the case of errata. Users can use kernel command line options to either disable a feature, or to force enable a feature that was disabled by a quirk. A different approach is needed for hardware features that do not have an X86_FEATURE_* flag. Update parsing of the "rdt=" boot parameter to call the telemetry driver directly to handle new "perf" and "energy" options that controls activation of telemetry monitoring of the named type. By itself a "perf" or "energy" option controls the forced enabling or disabling (with ! prefix) of all event groups of the named type. A ":guid" suffix allows for fine grained control per event group.

ata: libata: Add libata.force parameter max_sec
Add a new libata.force parameter called max_sec. The parameter can take an arbitrary value using the format: libata.force=max_sec=<number of 512B sectors> e.g. libata.force=max_sec=8191 or libata.force=max_sec=2048 This will allow the user to set an arbitrary maximum command size (dev->max_sectors) using libata.force. We cannot remove the existing libata.force parameters "max_sec_128" and "max_sec_1024", as these are a part of the exising user facing API.

Handover. Also preparation for LUO.
- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

mm/mm_init: Introduce a boot parameter for check_pages
Use-after-free and double-free bugs can be very difficult to track down.
The kernel is good at tracking these and preventing bad pages from being
used/created through simple checks gated behind "check_pages_enabled".
Currently, the only ways to enable this flag is by building with
CONFIG_DEBUG_VM, or as a side effect of other checks such as
init_on_{alloc, free}, page_poisoning, or debug_pagealloc among others.
These solutions are powerful, but may often be too coarse in balancing
the performance vs. safety that a user may want, particularly in
latency-sensitive production environments.
Introduce a new boot parameter "check_pages", which enables page checking
with no other side effects. It takes kstrbool-able inputs as an argument
(i.e. 0/1, true/false, on/off, ...). This patch is backwards-compatible;
setting CONFIG_DEBUG_VM still enables page checking.

Networking changes for 6.19.
Core & protocols
----------------
- Replace busylock at the Tx queuing layer with a lockless list. Resulting
in a 300% (4x) improvement on heavy TX workloads, sending twice the
number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue. Normally we perform queue re-selection when flow comes out
of idle, but under extreme circumstances the flows may be constantly
busy. Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already did
for Rx skbs).

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Replace busylock at the Tx queuing layer with a lockless list.
Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.
Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.
Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).

This has been another busy cycle for documentation, with a lot of
build-system thrashing. That work should slow down from here on out.
- The various scripts and tools for documentation were spread out in
several directories; now they are (almost) all coalesced under
tools/docs/. The holdout is the kernel-doc script, which cannot be
easily moved without some further thought.
- As the amount of Python code increases, we are accumulating modules that
are imported by multiple programs. These modules have been pulled
together under tools/lib/python/ -- at least, for documentation-related
programs. There is other Python code in the tree that might eventually
want to move toward this organization.
- The Perl kernel-doc.pl script has been removed. It is no longer used by
default, and nobody has missed it, least of all anybody who actually had
to look at it.
- The docs build was controlled by a complex mess of makefilese that few
dared to touch. Mauro has moved that logic into a new program
(tools/docs/sphinx-build-wrapper) that, with any luck at all, will be far
easier to understand and maintain.
- The get_feat.pl program, used to access information under
Documentation/features/, has been rewritten in Python, bringing an end to
the use of Perl in the docs subsystem.
- The top-level README file has been reorganized into a more
reader-friendly presentation.
- A lot of Chinese translation additions
- Typo fixes and documentation updates as usual

Pull power management updates from Rafael Wysocki:
"There are quite a few interesting things here, including new hardware
support, new features, some bug fixes and documentation updates. In
addition, there are a usual bunch of minor fixes and cleanups all
over.
In the new hardware support category, there are intel_pstate and
intel_rapl driver updates to support new processors, Panther Lake,
Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and
bandwidth allocation support in the tegra186 cpufreq driver, and
JH7110S SOC support in dt-platdev cpufreq.
The new features are the PM QoS CPU latency limit for suspend-to-idle,
the netlink support for the energy model management, support for
terminating system suspend via a wakeup event during the sync of file
systems, configurable number of hibernation compression threads, the
runtime PM auto-cleanup macros, and the "poweroff" PM event that is
expected to be used during system shutdown.
Bugs are mostly fixed in cpuidle governors, but there are also fixes
elsewhere, like in the amd-pstate cpufreq driver.
Documentation updates include, but are not limited to, a new doc on
debugging shutdown hangs, cross-referencing fixes and cleanups in the
intel_pstate documentation, and updates of comments in the core
hibernation code.
Specifics:
- Introduce and document a QoS limit on CPU exit latency during
wakeup from suspend-to-idle (Ulf Hansson)
- Add support for building libcpupower statically (Zuo An)
- Add support for sending netlink notifications to user space on

debugfs: Remove broken no-mount mode
debugfs access modes were added in Linux 5.10 (Dec 2020) [1], but the no-mount mode has behaved effectively the same as the off mode since Linux 5.12 (Apr 2021) [2]. The only difference is the specific error code returned by the debugfs_create_* functions, which is -ENOENT in no-mount mode and -EPERM in off mode. Given that no-mount hasn't worked for several years with no complaints, just remove it. [1] |

sys_info: add a default kernel sys_info mask
Which serves as a global default sys_info mask. When users want the same system information for many error cases (panic, hung, lockup ...), they can chose to set this global knob only once, while not setting up each individual sys_info knobs. This just adds a 'lazy' option, and doesn't change existing kernel behavior as the mask is 0 by default.

docs: panic: correct some sys_ifo names in sysctl doc
Patch series "Enable hung_task and lockup cases to dump system info on
demand", v2.
When working on kernel stability issues: panic, task-hung and soft/hard
lockup are frequently met. And to debug them, user may need lots of
system information at that time, like task call stacks, lock info, memory
info, ftrace dump, etc.
panic case already uses sys_info() for this purpose, and has a
'panic_sys_info' sysctl(also support cmdline setup) interface to take
human readable string like "tasks,mem,timers,locks,ftrace,..." to control
what kinds of information is needed. Which is also helpful to debug
task-hung and lockup cases.
So this patchset introduces the similar sys_info sysctl interface for
task-hung and lockup cases.
his is mainly for debugging and the info dumping could be intrusive, like
dumping call stack for all tasks when system has huge number of tasks,
similarly for ftrace dump (we may add tracing_stop() and tracing_start()
around it)
Locally these have been used in our bug chasing for stability issues and
were helpful.
As Andrew suggested, add a configurable global 'kernel_sys_info' knob.
When error scenarios like panic/hung-task/lockup etc doesn't setup their
own sys_info knob and calls sys_info() with parameter "0", this global
knob will take effect. It could be used for other kernel cases like OOM,
which may not need one dedicated sys_info knob.
This patch (of 4):
Some sys_info names wered forgotten to change in patch iterations, while
the right names are defined in kernel/sys_info.c.

dm verity fec: Expose corrected block count via status
Enhance visibility into dm-verity Forward Error Correction (FEC) activity. While FEC can correct on-disk corruptions, the number of successful correction events is not readily exposed through a standard interface. This change integrates FEC statistics into the verity target's .status handler for STATUSTYPE_INFO. The info output now includes count of corrected block by FEC. The counter is a per-device instance atomic64_t, maintained within the struct dm_verity_fec, tracking blocks successfully repaired by FEC on this specific device instance since it was created. This approach aligns with the standard Device Mapper mechanism for targets to report runtime information, as used by other targets like dm-integrity. This patch also updates Documentation/admin-guide/device-mapper/verity.rst to reflect the new status information. Tested: Induced single-bit errors on a block device protected by dm-verity with FEC on android phone. Confirmed 'dmctl status <device>' on Android reports an incrementing 'fec_corrected_blocks' count after the corrupted blocks were accessed.

mm/swap: do not choose swap device according to numa node
Patch series "mm/swapfile.c: select swap devices of default priority round robin", v5. Currently, on system with multiple swap devices, swap allocation will select one swap device according to priority. The swap device with the highest priority will be chosen to allocate firstly. People can specify a priority from 0 to 32767 when swapon a swap device, or the system will set it from -2 then downwards by default. Meanwhile, on NUMA system, the swap device with node_id will be considered first on that NUMA node of the node_id. In the current code, an array of plist, swap_avail_heads[nid], is used to organize swap devices on each NUMA node. For each NUMA node, there is a plist organizing all swap devices. The 'prio' value in the plist is the negated value of the device's priority due to plist being sorted from low to high. The swap device owning one node_id will be promoted to the front position on that NUMA node, then other swap devices are put in order of their default priority. E.g I got a system with 8 NUMA nodes, and I setup 4 zram partition as swap devices. Current behaviour: their priorities will be(note that -1 is skipped): NAME TYPE SIZE USED PRIO /dev/zram0 partition 16G 0B -2 /dev/zram1 partition 16G 0B -3 /dev/zram2 partition 16G 0B -4 /dev/zram3 partition 16G 0B -5 And their positions in the 8 swap_avail_lists[nid] will be: swap_avail_lists[0]: /* node 0's available swap device list */ zram0 -> zram1 -> zram2 -> zram3 prio:1 prio:3 prio:4 prio:5 swap_avali_lists[1]: /* node 1's available swap device list */ zram1 -> zram0 -> zram2 -> zram3 prio:1 prio:2 prio:4 prio:5 swap_avail_lists[2]: /* node 2's available swap device list */ zram2 -> zram0 -> zram1 -> zram3 prio:1 prio:2 prio:3 prio:5 swap_avail_lists[3]: /* node 3's available swap device list */ zram3 -> zram0 -> zram1 -> zram2 prio:1 prio:2 prio:3 prio:4 swap_avail_lists[4-7]: /* node 4,5,6,7's available swap device list */ zram0 -> zram1 -> zram2 -> zram3 prio:2 prio:3 prio:4 prio:5 The adjustment for swap device with node_id intended to decrease the pressure of lock contention for one swap device by taking different swap device on different node. The adjustment was introduced in commit |

mm: shmem/tmpfs hugepage defaults config choice
Allow to override defaults for shemem and tmpfs at config time. This is consistent with how transparent hugepages can be configured. Same results can be achieved with the existing 'transparent_hugepage_shmem' and 'transparent_hugepage_tmpfs' settings in the kernel command line, but it is more convenient to define basic settings at config time instead of changing kernel command line later. Defaults for shmem and tmpfs were not changed. They are remained the same as before: 'never' for both cases. Options 'deny' and 'force' are omitted intentionally since these are special values and supposed to be used for emergencies or testing and are not expected to be permanent ones. Primary motivation for adding config option is to enable policy enforcement at build time. In large-scale production environments (Meta's for example), the kernel configuration is often maintained centrally close to the kernel code itself and owned by the kernel engineers, while boot parameters are managed independently (e.g. by provisioning systems). In such setups, the kernel build defines the supported and expected behavior in a single place, but there is no reliable or uniform control over the kernel command line options. A build-time default allows kernel integrators to enforce a predictable hugepage policy for shmem/tmpfs on a base layer, ensuring reproducible behavior and avoiding configuration drift caused by possible boot-time differences. In short, primary benefit is mostly operational: it provides a way to codify preferred policy in the kernel configuration, which is versioned, reviewed, and tested as part of the kernel build process, rather than depending on potentially variable boot parameters.

memcg: net: track network throttling due to memcg memory pressure
The kernel can throttle network sockets if the memory cgroup associated with the corresponding socket is under memory pressure. The throttling actions include clamping the transmit window, failing to expand receive or send buffers, aggressively prune out-of-order receive queue, FIN deferred to a retransmitted packet and more. Let's add memcg metric to track such throttling actions. At the moment memcg memory pressure is defined through vmpressure and in future it may be defined using PSI or we may add more flexible way for the users to define memory pressure, maybe through ebpf. However the potential throttling actions will remain the same, so this newly introduced metric will continue to track throttling actions irrespective of how memcg memory pressure is defined.

dynamic_debug: add support for print stack
In practical problem diagnosis, especially during the boot phase, it is often desirable to know the call sequence. However, currently, apart from adding print statements and recompiling the kernel, there seems to be no good alternative. If dynamic_debug supported printing the call stack, it would be very helpful for diagnosing issues. This patch add support '+d' for dump stack.

hung_task: panic when there are more than N hung tasks at the same time
The hung_task_panic sysctl is currently a blunt instrument: it's all or nothing. Panicking on a single hung task can be an overreaction to a transient glitch. A more reliable indicator of a systemic problem is when multiple tasks hang simultaneously. Extend hung_task_panic to accept an integer threshold, allowing the kernel to panic only when N hung tasks are detected in a single scan. This provides finer control to distinguish between isolated incidents and system-wide failures. The accepted values are: - 0: Don't panic (unchanged) - 1: Panic on the first hung task (unchanged) - N > 1: Panic after N hung tasks are detected in a single scan The original behavior is preserved for values 0 and 1, maintaining full backward compatibility.

md: allow configuring logical block size
Previously, raid array used the maximum logical block size (LBS) of all member disks. Adding a larger LBS disk at runtime could unexpectedly increase RAID's LBS, risking corruption of existing partitions. This can be reproduced by: ``` # LBS of sd[de] is 512 bytes, sdf is 4096 bytes. mdadm -CRq /dev/md0 -l1 -n3 /dev/sd[de] missing --assume-clean # LBS is 512 cat /sys/block/md0/queue/logical_block_size # create partition md0p1 parted -s /dev/md0 mklabel gpt mkpart primary 1MiB 100% lsblk | grep md0p1 # LBS becomes 4096 after adding sdf mdadm --add -q /dev/md0 /dev/sdf cat /sys/block/md0/queue/logical_block_size # partition lost partprobe /dev/md0 lsblk | grep md0p1 ``` Simply restricting larger-LBS disks is inflexible. In some scenarios, only disks with 512 bytes LBS are available currently, but later, disks with 4KB LBS may be added to the array. Making LBS configurable is the best way to solve this scenario. After this patch, the raid will: - store LBS in disk metadata - add a read-write sysfs 'mdX/logical_block_size' Future mdadm should support setting LBS via metadata field during RAID creation and the new sysfs. Though the kernel allows runtime LBS changes, users should avoid modifying it after creating partitions or filesystems to prevent compatibility issues. Only 1.x metadata supports configurable LBS. 0.90 metadata inits all fields to default values at auto-detect. Supporting 0.90 would require more extensive changes and no such use case has been observed. Note that many RAID paths rely on PAGE_SIZE alignment, including for metadata I/O. A larger LBS than PAGE_SIZE will result in metadata read/write failures. So this config should be prevented.

PM: hibernate: make compression threads configurable
The number of compression/decompression threads has a direct impact on
hibernate image generation and resume latency. Using more threads can
reduce overall resume time, but on systems with fewer CPU cores it may
also introduce contention and reduce efficiency.
Performance was evaluated on an 8-core ARM system, averaged over 10 runs:
Threads Hibernate(s) Resume(s)
--------------------------------
3 12.14 18.86
4 12.28 17.48
5 11.09 16.77
6 11.08 16.44
With 5–6 threads, resume latency improves by approximately 12% compared
to the default 3-thread configuration, with negligible impact on
hibernate time.
Introduce a new kernel parameter `hibernate_compression_threads=` that
allows users and integrators to tune the number of
compression/decompression threads at boot. This provides a way to
balance performance and CPU utilization across a wide range of hardware
without recompiling the kernel.

Documentation: intel_pstate: fix duplicate hyperlink target errors
Fix reST warnings in
Documentation/admin-guide/pm/intel_pstate.rst caused by missing explicit
hyperlink labels for section titles.
Before this change, the following errors were printed during
`make htmldocs`:
Documentation/admin-guide/pm/intel_pstate.rst:401:
ERROR: Indirect hyperlink target (id="id6") refers to target
"passive mode", which is a duplicate, and cannot be used as a
unique reference.
Documentation/admin-guide/pm/intel_pstate.rst:517:
ERROR: Indirect hyperlink target (id="id9") refers to target
"active mode", which is a duplicate, and cannot be used as a
unique reference.
Documentation/admin-guide/pm/intel_pstate.rst:611:
ERROR: Indirect hyperlink target (id="id15") refers to target
"global attributes", which is a duplicate, and cannot be used as
a unique reference.
ERROR: Duplicate target name, cannot be used as a unique reference:
"passive mode", "active mode", "global attributes".
These errors occurred because the sections "Active Mode",
"Active Mode With HWP", "Passive Mode", and "Global Attributes"
did not define explicit hyperlink labels. As a result, Sphinx
auto-generated duplicate anchors when the same titles appeared
multiple times within the document.
Because of this, the generated HTML documentation contained
broken references such as:
`active mode <Active Mode_>`_
`passive mode <Passive Mode_>`_
`global attributes <Global Attributes_>`_
This patch adds explicit hyperlink labels for the affected sections,
ensuring all references are unique and correctly resolved.
After applying this patch, `make htmldocs` completes without
any warnings, and all hyperlinks in intel_pstate.html render properly.

net: Introduce net.core.bypass_prot_mem sysctl.
If a socket has sk->sk_bypass_prot_mem flagged, the socket opts out of the global protocol memory accounting. Let's control the flag by a new sysctl knob. The flag is written once during socket(2) and is inherited to child sockets. Tested with a script that creates local socket pairs and send()s a bunch of data without recv()ing.

More power management updates for 6.18-rc1
- Make cpufreq drivers setting the default CPU transition latency to
CPUFREQ_ETERNAL specify a proper default transition latency value
instead which addresses a regression introduced during the 6.6 cycle
that broke CPUFREQ_ETERNAL handling (Rafael Wysocki)
- Make the cpufreq CPPC driver use a proper transition delay value
when CPUFREQ_ETERNAL is returned by cppc_get_transition_latency() to
indicate an error condition (Rafael Wysocki)
- Make cppc_get_transition_latency() return a negative error code to
indicate error conditions instead of using CPUFREQ_ETERNAL for this
purpose and drop CPUFREQ_ETERNAL that has no other users (Rafael
Wysocki, Gopi Krishna Menon)
- Fix device leak in the mediatek cpufreq driver (Johan Hovold)
- Set target frequency on all CPUs sharing a policy during frequency
updates in the tegra186 cpufreq driver and make it initialize all
cores to max frequencies (Aaron Kling)
- Rust cpufreq helper cleanup (Thorsten Blum)
- Make pm_runtime_put*() family of functions return 1 when the
given device is already suspended which is consistent with the
documentation (Brian Norris)
- Add basic kunit tests for runtime PM API contracts and update return
values in kerneldoc comments for the runtime PM API (Brian Norris,
Dan Carpenter)
- Add auto-cleanup macros for runtime PM "resume and get" and "get
without resume" operations, use one of them in the PCI core and
drop the existing "free" macro introduced for similar purpose, but
somewhat cumbersome to use (Rafael Wysocki)
- Make the core power management code avoid waiting on device links
marked as SYNC_STATE_ONLY which is consistent with the handling of
those device links elsewhere (Pin-yen Lin)

Generic:
* Rework almost all of KVM's exports to expose symbols only to KVM's x86
vendor modules (kvm-{amd,intel}.ko and PPC's kvm-{pr,hv}.ko.
x86:
* Rework almost all of KVM x86's exports to expose symbols only to KVM's
vendor modules, i.e. to kvm-{amd,intel}.ko.
* Add support for virtualizing Control-flow Enforcement Technology (CET) on
Intel (Shadow Stacks and Indirect Branch Tracking) and AMD (Shadow Stacks).
It's worth noting that while SHSTK and IBT can be enabled separately in CPUID,
it is not really possible to virtualize them separately. Therefore, Intel
processors will really allow both SHSTK and IBT under the hood if either is
made visible in the guest's CPUID. The alternative would be to intercept
XSAVES/XRSTORS, which is not feasible for performance reasons.
* Fix a variety of fuzzing WARNs all caused by checking L1 intercepts when
completing userspace I/O. KVM has already committed to allowing L2 to
to perform I/O at that point.
* Emulate PERF_CNTR_GLOBAL_STATUS_SET for PerfMonV2 guests, as the MSR is
supposed to exist for v2 PMUs.
* Allow Centaur CPU leaves (base 0xC000_0000) for Zhaoxin CPUs.
* Add support for the immediate forms of RDMSR and WRMSRNS, sans full
emulator support (KVM should never need to emulate the MSRs outside of
forced emulation and other contrived testing scenarios).
* Clean up the MSR APIs in preparation for CET and FRED virtualization, as
well as mediated vPMU support.
* Clean up a pile of PMU code in anticipation of adding support for mediated
vPMUs.
* Reject in-kernel IOAPIC/PIT for TDX VMs, as KVM can't obtain EOI vmexits
needed to faithfully emulate an I/O APIC for such guests.
* Many cleanups and minor fixes.
* Recover possible NX huge pages within the TDP MMU under read lock to
reduce guest jitter when restoring NX huge pages.
* Return -EAGAIN during prefault if userspace concurrently deletes/moves the
relevant memslot, to fix an issue where prefaulting could deadlock with the
memslot update.
x86 (AMD):
* Enable AVIC by default for Zen4+ if x2AVIC (and other prereqs) is supported.
* Require a minimum GHCB version of 2 when starting SEV-SNP guests via
KVM_SEV_INIT2 so that invalid GHCB versions result in immediate errors
instead of latent guest failures.
* Add support for SEV-SNP's CipherText Hiding, an opt-in feature that prevents
unauthorized CPU accesses from reading the ciphertext of SNP guest private
memory, e.g. to attempt an offline attack. This feature splits the shared
SEV-ES/SEV-SNP ASID space into separate ranges for SEV-ES and SEV-SNP guests,
therefore a new module parameter is needed to control the number of ASIDs
that can be used for VMs with CipherText Hiding vs. how many can be used to
run SEV-ES guests.
* Add support for Secure TSC for SEV-SNP guests, which prevents the untrusted
host from tampering with the guest's TSC frequency, while still allowing the
the VMM to configure the guest's TSC frequency prior to launch.
* Validate the XCR0 provided by the guest (via the GHCB) to avoid bugs
resulting from bogus XCR0 values.
* Save an SEV guest's policy if and only if LAUNCH_START fully succeeds to
avoid leaving behind stale state (thankfully not consumed in KVM).
* Explicitly reject non-positive effective lengths during SNP's LAUNCH_UPDATE
instead of subtly relying on guest_memfd to deal with them.
* Reload the pre-VMRUN TSC_AUX on #VMEXIT for SEV-ES guests, not the host's
desired TSC_AUX, to fix a bug where KVM was keeping a different vCPU's
TSC_AUX in the host MSR until return to userspace.
KVM (Intel):
* Preparation for FRED support.
* Don't retry in TDX's anti-zero-step mitigation if the target memslot is
invalid, i.e. is being deleted or moved, to fix a deadlock scenario similar
to the aforementioned prefaulting case.
* Misc bugfixes and minor cleanups.

It has been a relatively busy cycle in docsland, with changes all over:
- Bring the kernel memory-model docs into the Sphinx build in the "literal
include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate HTML
redirects; this can be used on kernel.org (or any other site hosting the

Merge tag 'docs-6.18' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle in docsland, with changes all
over:
- Bring the kernel memory-model docs into the Sphinx build in the
"literal include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate
HTML redirects; this can be used on kernel.org (or any other site
hosting the rendered docs) to avoid breaking links.
- Automated processing of the YAML files describing the netlink
protocol.
- A significant update of the maintainer's PGP guide.
... and a seemingly endless series of typo fixes, build-problem fixes,
etc"

Summary of significant series in this pull request:
- The 3 patch series "mm, swap: improve cluster scan strategy" from Kairui Song improves performance and reduces the failure rate of swap cluster allocation. - The 4 patch series "support large align and nid in Rust allocators" from Vitaly Wool permits Rust allocators to set NUMA node and large alignment when perforning slub and vmalloc reallocs. - The 2 patch series "mm/damon/vaddr: support stat-purpose DAMOS" from Yueyang Pan extend DAMOS_STAT's handling of the DAMON operations sets for virtual address spaces for ops-level DAMOS filters. - The 3 patch series "execute PROCMAP_QUERY ioctl under per-vma lock" from Suren Baghdasaryan reduces mmap_lock contention during reads of /proc/pid/maps. - The 2 patch series "mm/mincore: minor clean up for swap cache checking" from Kairui Song performs some cleanup in the swap code. - The 11 patch series "mm: vm_normal_page*() improvements" from David Hildenbrand provides code cleanup in the pagemap code. - The 5 patch series "add persistent huge zero folio support" from Pankaj Raghav provides a block layer speedup by optionalls making the huge_zero_pagepersistent, instead of releasing it when its refcount falls to zero. - The 3 patch series "kho: fixes and cleanups" from Mike Rapoport adds a few touchups to the recently added Kexec Handover feature. - The 10 patch series "mm: make mm->flags a bitmap and 64-bit on all arches" from Lorenzo Stoakes turns mm_struct.flags into a bitmap. To end the constant struggle with space shortage on 32-bit conflicting with 64-bit's needs. - The 2 patch series "mm/swapfile.c and swap.h cleanup" from Chris Li cleans up some swap code. - The 7 patch series "selftests/mm: Fix false positives and skip unsupported tests" from Donet Tom fixes a few things in our selftests code. - The 7 patch series "prctl: extend PR_SET_THP_DISABLE to only provide THPs when advised" from David Hildenbrand "allows individual processes to opt-out of THP=always into THP=madvise, without affecting other workloads on the system". It's a long story - the [1/N] changelog spells out the considerations. - The 11 patch series "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on the memdesc project. Please see https://kernelnewbies.org/MatthewWilcox/Memdescs and https://blogs.oracle.com/linux/post/introducing-memdesc. - The 3 patch series "Tiny optimization for large read operations" from Chi Zhiling improves the efficiency of the pagecache read path. - The 5 patch series "Better split_huge_page_test result check" from Zi Yan improves our folio splitting selftest code. - The 2 patch series "test that rmap behaves as expected" from Wei Yang adds some rmap selftests. - The 3 patch series "remove write_cache_pages()" from Christoph Hellwig removes that function and converts its two remaining callers. - The 2 patch series "selftests/mm: uffd-stress fixes" from Dev Jain fixes some UFFD selftests issues. - The 3 patch series "introduce kernel file mapped folios" from Boris Burkov introduces the concept of "kernel file pages". Using these permits btrfs to account its metadata pages to the root cgroup, rather than to the cgroups of random inappropriate tasks. - The 2 patch series "mm/pageblock: improve readability of some pageblock handling" from Wei Yang provides some readability improvements to the page allocator code. - The 11 patch series "mm/damon: support ARM32 with LPAE" from SeongJae Park teaches DAMON to understand arm32 highmem. - The 4 patch series "tools: testing: Use existing atomic.h for vma/maple tests" from Brendan Jackman performs some code cleanups and deduplication under tools/testing/. - The 2 patch series "maple_tree: Fix testing for 32bit compiles" from Liam Howlett fixes a couple of 32-bit issues in tools/testing/radix-tree.c. - The 2 patch series "kasan: unify kasan_enabled() and remove arch-specific implementations" from Sabyrzhan Tasbolatov moves KASAN arch-specific initialization code into a common arch-neutral implementation. - The 3 patch series "mm: remove zpool" from Johannes Weiner removes zspool - an indirection layer which now only redirects to a single thing (zsmalloc). - The 2 patch series "mm: task_stack: Stack handling cleanups" from Pasha Tatashin makes a couple of cleanups in the fork code. - The 37 patch series "mm: remove nth_page()" from David Hildenbrand makes rather a lot of adjustments at various nth_page() callsites, eventually permitting the removal of that undesirable helper function. - The 2 patch series "introduce kasan.write_only option in hw-tags" from Yeoreum Yun creates a KASAN read-only mode for ARM, using that architecture's memory tagging feature. It is felt that a read-only mode KASAN is suitable for use in production systems rather than debug-only. - The 3 patch series "mm: hugetlb: cleanup hugetlb folio allocation" from Kefeng Wang does some tidying in the hugetlb folio allocation code. - The 12 patch series "mm: establish const-correctness for pointer parameters" from Max Kellermann makes quite a number of the MM API functions more accurate about the constness of their arguments. This was getting in the way of subsystems (in this case CEPH) when they attempt to improving their own const/non-const accuracy. - The 7 patch series "Cleanup free_pages() misuse" from Vishal Moola fixes a number of code sites which were confused over when to use free_pages() vs __free_pages(). - The 3 patch series "Add Rust abstraction for Maple Trees" from Alice Ryhl makes the mapletree code accessible to Rust. Required by nouveau and by its forthcoming successor: the new Rust Nova driver. - The 2 patch series "selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and some cleanups to the thp selftesting code. - The 14 patch series "mm, swap: introduce swap table as swap cache (phase I)" from Chris Li and Kairui Song is the first step along the path to implementing "swap tables" - a new approach to swap allocation and state tracking which is expected to yield speed and space improvements. This patchset itself yields a 5-20% performance benefit in some situations. - The 3 patch series "Some ptdesc cleanups" from Matthew Wilcox utilizes the new memdesc layer to clean up the ptdesc code a little. - The 3 patch series "Fix va_high_addr_switch.sh test failure" from Chunyu Hu fixes some issues in our 5-level pagetable selftesting code. - The 2 patch series "Minor fixes for memory allocation profiling" from Suren Baghdasaryan addresses a couple of minor issues in relatively new memory allocation profiling feature. - The 3 patch series "Small cleanups" from Matthew Wilcox has a few cleanups in preparation for more memdesc work. - The 2 patch series "mm/damon: add addr_unit for DAMON_LRU_SORT and DAMON_RECLAIM" from Quanmin Yan makes some changes to DAMON in furtherance of supporting arm highmem. - The 2 patch series "selftests/mm: Add -Wunreachable-code and fix warnings" from Muhammad Anjum adds that compiler check to selftests code and fixes the fallout, by removing dead code. - The 10 patch series "Improvements to Victim Process Thawing and OOM Reaper Traversal Order" from zhongjinji makes a number of improvements in the OOM killer: mainly thawing a more appropriate group of victim threads so they can release resources. - The 5 patch series "mm/damon: misc fixups and improvements for 6.18" from SeongJae Park is a bunch of small and unrelated fixups for DAMON. - The 7 patch series "mm/damon: define and use DAMON initialization check function" from SeongJae Park implement reliability and maintainability improvements to a recently-added bug fix. - The 2 patch series "mm/damon/stat: expose auto-tuned intervals and non-idle ages" from SeongJae Park provides additional transparency to userspace clients of the DAMON_STAT information. - The 2 patch series "Expand scope of khugepaged anonymous collapse" from Dev Jain removes some constraints on khubepaged's collapsing of anon VMAs. It also increases the success rate of MADV_COLLAPSE against an anon vma. - The 2 patch series "mm: do not assume file == vma->vm_file in compat_vma_mmap_prepare()" from Lorenzo Stoakes moves us further towards removal of file_operations.mmap(). This patchset concentrates upon clearing up the treatment of stacked filesystems. - The 6 patch series "mm: Improve mlock tracking for large folios" from Kiryl Shutsemau provides some fixes and improvements to mlock's tracking of large folios. /proc/meminfo's "Mlocked" field became more accurate. - The 2 patch series "mm/ksm: Fix incorrect accounting of KSM counters during fork" from Donet Tom fixes several user-visible KSM stats inaccuracies across forks and adds selftest code to verify these counters. - The 2 patch series "mm_slot: fix the usage of mm_slot_entry" from Wei Yang addresses some potential but presently benign issues in KSM's mm_slot handling. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCaN3cywAKCRDdBJ7gKXxA jtaPAQDmIuIu7+XnVUK5V11hsQ/5QtsUeLHV3OsAn4yW5/3dEQD/UddRU08ePN+1 2VRB0EwkLAdfMWW7TfiNZ+yhuoiL/AA= =4mhY -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-10-01-19-00' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - "mm, swap: improve cluster scan strategy" from Kairui Song improves performance and reduces the failure rate of swap cluster allocation - "support large align and nid in Rust allocators" from Vitaly Wool permits Rust allocators to set NUMA node and large alignment when perforning slub and vmalloc reallocs - "mm/damon/vaddr: support stat-purpose DAMOS" from Yueyang Pan extend DAMOS_STAT's handling of the DAMON operations sets for virtual address spaces for ops-level DAMOS filters - "execute PROCMAP_QUERY ioctl under per-vma lock" from Suren Baghdasaryan reduces mmap_lock contention during reads of /proc/pid/maps - "mm/mincore: minor clean up for swap cache checking" from Kairui Song performs some cleanup in the swap code - "mm: vm_normal_page*() improvements" from David Hildenbrand provides code cleanup in the pagemap code - "add persistent huge zero folio support" from Pankaj Raghav provides a block layer speedup by optionalls making the huge_zero_pagepersistent, instead of releasing it when its refcount falls to zero - "kho: fixes and cleanups" from Mike Rapoport adds a few touchups to the recently added Kexec Handover feature - "mm: make mm->flags a bitmap and 64-bit on all arches" from Lorenzo Stoakes turns mm_struct.flags into a bitmap.
