mm.git review status for linus..mm-stable
Everything: Total patches: 171 Reviews/patch: 1.83 Reviewed rate: 82% Excluding selftests: Total patches: 149 Reviews/patch: 1.77 Reviewed rate: 80% Excluding selftests and maple_tree: Total patches: 129 Reviews/patch: 1.99 Reviewed rate: 89% Summary of patch series in this merge: - "mm/rmap: index MAP_PRIVATE file-backed folios by anonymous pgoff" (Lorenzo Stoakes): Index MAP_PRIVATE file-backed folios by their anonymous page offset to resolve confusion around reverse mapping for zeroed and CoW'd file-backed memory. Use this new VMA anonymous page offset tracking to eliminate index conflicts and lay the foundation for scalable CoW performance improvements. - "promote mapped executable folios after first usage for MGLRU" (Baolin Wang): Make MGLRU's protection of mapped executable file folios more reliable. Follow the classical LRU's logic, promoting mapped executable file folios after their first usage to give executable code a better chance to stay in memory and improve workload performance. - "mm: vmscan: fix node reclaim ignoring swappiness parameter" (Ridong Chen): Fix per-node proactive reclaim interface's ignoring the swappiness parameter when CONFIG_MEMCG is disabled by consolidating sc_swappiness() into a single function that checks proactive_swappiness regardless of kernel configuration. - "mm/vmscan: reduce lru_lock contention via vmstat-derived scan-balance cost" (Usama Arif): Reduce lru_lock contention in the reclaim path by deriving scan-balance costs from vmstat counters rather than lock-acquired producer updates. Read and decay these cost signals on the reclaim side under a dedicated per-lruvec lock, reducing total LRU lock wait time by over 60% without impacting scan throughput. - "zram: fix zram issues reported by sashiko" (Sergey Senozhatsky): Fix two low-risk zram bugs which Sashiko spotted in drive-by review. - "Honor XA_FLAGS_ACCOUNT in xas_split_alloc() and charge to folio's memcg" (Zi Yan): Fix xas_split_alloc() by enabling target folio memcg charging during splits and adding the missing __GFP_ACCOUNT flag for proper XArray node memory accounting. - "selftests/mm: use pattern matching in .gitignore" (Pratyush Mallick): Replace hardcoded binary names in selftests/mm/.gitignore with a generic pattern-matching rule to automatically ignore generated test files and avoid manual updates when adding new tests. - "mm/page_ext: remove pgdat_page_ext_init()" (Sang-Heon Jeon): Make the incompatibility between FLATMEM and NUMA explicit in mm/Kconfig and remove the unused pgdat_page_ext_init() function. - "zram: fix zstd error paths and add parameter validation" (Haoqin Huang): Clean up zram compression backends by removing redundant error cleanup, adding parameter and dictionary validation, auto-prefixing algorithm error logs, and resetting parameters prior to reinitialization. - "zram: fix stale scan bounds after reinitialization" (Longlong Xia): Prevent out-of-bounds slot accesses during concurrent zram resets by moving table scan bound calculations under dev_lock in writeback_store() and read_block_state(). - "add anon mTHP collapse test cases" (Baolin Wang): Extend selftests helper functions to support arbitrary page orders and add new test cases and options for mTHP collapse in khugepaged. - "selftests/mm: Handle unsupported and transient test conditions" (Muhammad Usama Anjum): Update MM selftests to report a SKIP status instead of a failure when required kernel or filesystem features are unsupported, while adding retry logic for transient page migration errors. - "mm/zswap: Fixes and improves the zswap shrink" (Hao Jia): Fix the missing zswap global shrinker when CONFIG_MEMCG is disabled and extend shrink_memcg() to support batch writeback for improved writeback efficiency. - "alloc_tag: introduce IOCTL-based filtering for MAP" (Suren Baghdasaryan): Introduce an IOCTL-based binary interface for memory allocation profiling that enables kernel-side filtering before per-CPU counter aggregation. This eliminates the text-parsing overhead of /proc/allocinfo and provides up to a 20x speedup by transferring only filtered allocation data to userspace. - "better block swap batching and a different take on swap_ops v5" (Christoph Hellwig): Refactor block swap I/O to use swap_iocb for batching instead of single-bio requests and rebase the swap_ops interface, achieving faster swap throughput during kernel builds. - "mm: kmemleak: reduce transient false positives by confirming leaks" (Catalin Marinas): Reduce false-positive kmemleak reports by combining two kmemleak enhancements that add a second confirmation scan and a configurable minimum unreferenced scan count module parameter. - "mm: kmemleak: default min_unref_scans to 2 for verbose kernels" (Breno Leitao): Auto-scanning kernels can generate false-positive memory leak reports on single scans, so this patch defaults min_unref_scans to 2 when CONFIG_DEBUG_KMEMLEAK_VERBOSE is enabled to require a second confirming scan. - "swap_ops updates" (Christoph Hellwig): Batching I/O for synchronous swap devices causes performance regressions and filesystem-based swap suffers from double-indirection overhead. This series resolves both issues by reintroducing per-folio writes for synchronous swap and allowing filesystems to directly export their own swap_ops. - "mm/khugepaged: several cleanups" (Nico Pache): khugepaged accumulated redundant state-checking patterns and outdated comments following mTHP integration. Introduce dedicated helpers for PTE validation and event counting while refreshing the internal documentation. - "maple_tree: lock checking and clean ups" (Liam Howlett): Syzbot reports incorrectly blame memory management exit paths for locking bugs, maple tree erase operations risk allocation failures without gfp flags and internal documentation lacks clarity. Improve lock error detection, update docs, fix race and allocation edge cases and optimize erase allocations using a fallback to GFP_KERNEL | GFP_NOFAIL. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCao9nJQAKCRDdBJ7gKXxA jk/9AQDlfevYJuSJmzAI8bt8ISG+/TfXMtIZC/MdbHqtQVYWPQD8Cvm3DUZsdGB/ Gloq/HBFuMPgE8p2pwUIthdgnTPNvAc= =c+Nb -----END PGP SIGNATURE----- Merge tag 'mm-stable-2026-08-26-15-22' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull more MM updates from Andrew Morton: - "mm/rmap: index MAP_PRIVATE file-backed folios by anonymous pgoff" (Lorenzo Stoakes) Index MAP_PRIVATE file-backed folios by their anonymous page offset to resolve confusion around reverse mapping for zeroed and CoW'd file-backed memory.

runtime verification fix for 7.3:
- Use .old instead of .bak for rvgen kunit backup files The rvgen kunit command generates .bak backup files and these are checked in for selftests as "golden" files for make check. Clean make disclean removes such files, leaving the tree dirty. Switch to .old to preserve a clean tree after make disclean. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCao80ThQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qphQAQC/B9JUq0aHC/xcPyR+4kFG13jykotd h/0xV1e6nyExigEAtzx4Lc/JnUzXPVpmtabzOGHwMTklbDl9bfnZtOdEmQo= =MY27 -----END PGP SIGNATURE----- Merge tag 'trace-rv-v7.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull runtime verification fix from Steven Rostedt: - Use .old instead of .bak for rvgen kunit backup files The rvgen kunit command generates .bak backup files and these are checked in for selftests as "golden" files for make check.

Mostly the usual clk driver updates and new SoC additions plus non-critical
data fixes for things that weren't used yet. One thing that's new here in the core is SSC spread spectrum support (SSC) in the clk provider API. The idea is that DT authors will configure SSC for certain clks and they'll be configured at clk provider registration time or when a consumer device is probed, similar to how we handle assigned clk rates or parents. On the clk driver side we have Qualcomm adding almost half the diff because they add support for 4 different SoCs and then a long tail of other SoCs like Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more SoC support this time around. Luckily it's mostly clk data for these new SoCs because the actual clk_ops are already there. Beyond the new drivers we get all the little fixups for more compilation coverage or usage of more modern APIs. That all looks normal. Finally, I kinda buried the lead, I'm bringing on Brian and Jerome to help out with maintaining the clk subsystem. The current working model is already semi-distributed in that silicon vendors typically take care of their drivers and send me pull requests but I'm becoming a bottleneck for new drivers and core framework review because this has become a 100% volunteer effort on my part. Mike is stepping down after all these years (thanks Mike!) and that jump started the conversation around finding co-maintainers. Brian and Jerome have graciously offered to help me with the work load, meaning in the future they'll be sending pull requests and committing directly to the clk.git tree. They've both been around on the list for a while, I've met them both in person, and they've been making changes to the core clk framework along with helping review patches so I'm pretty confident this will work well.

Merge tag 'apparmor-pr-2026-08-26' of git://git.kernel.org/pub/scm/linux/kernel/git/jj/linux-apparmor
Pull AppArmor updates from John Johansen:
"The biggest functional change is Jann Horn's fix for how aparmor is
doing stale cred updates after a policy replacement.
apparmor: fix cred UAF caused by begin_current_label_crit_section()
It moves the update to be done during task_work at the end of the
syscall.
One major feature is allowing policy to be compressed in userspace
instead of after the fact (in kernel) if we need to hold onto it for
CRIU/introspection.
The other major change is to do with network mediation. It is a lot of
code churn but does not do any functional changes to mediation. It
moves the code around, and refactors it to use newer patterns for
consistency, and in preparation for some improvements in mediation in
a future patchset.
Features:
- support loading compressed policies
- add audit mode to provide a mechanism to silence complain messages
- refactor network mediation to use new patterns, and prepare to for
extended inet mediation (no functional change)
Cleanups:
- switch website link to https
- make include headers self-contained, and fix circular include
- constify aa_label, aa_dfa, aa_profile, and aa_perms paraneters
- mark static tables and structs as read only
- drop use of _confined variant for iteration
- refactory mount to use check_perms
- refactor network mediation code to be together
- refactor xattr attachment, to take the file path
- optimize current_label_crit_section()
- leverage audit_log_n_untrustedstring() when possible
Bug Fixes:
- initialized policy lists heads before fail path
- fix deadlock in complain-mode change_hat
- auditing of mount binary data
- fix error debug output in fn_label_build
- fix race condition in label replacement
- fix unconfined user namespace restriction forced stack
- fix error handling for copy_from_user in policy_update
- fix out-of-bounds write when null terminating a label vec
- fix integer overflow in verify_tags() bounds check
- fix cred UAF caused by begin_current_label_crit_section()
- use SEND_SIG_NOINFO instead of NULL in aa_audit()"

power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable()
The way power sequencing works means that a call to pwrseq_power_on() does not necessarily result in the pwrseq target being powered-on at that time: it may have already been powered on before. Similarly: a call to pwrseq_power_off() does not have to result in an actual powering off of resources: there may still be other users that requested a power-on before. We will also introduce the concept of "non-controllable" pwrseq targets soon which further increases the disconnect between the naming convention and the actual semantics. What consumers of pwrseq descriptors actually do is: they *vote* for a powering on of a given target or retract that vote. These operations could be called get/put in line with runtime PM but this could become confusing since we already provide pwrseq_get/put() for a different purpose. pwrseq_vote_on/off() also have been rejected as unusual in the tree. Change the name of the two functions to pwrseq_enable/disable() which better reflects their purpose and semantics and also mirrors other enable-counted resources like regulators and clocks. No functional change intended. If at any point users need to know *when* the exact power event happens, we can provide that information in the form of a notifier.

remoteproc updates for v7.3
Add a remoteproc driver and binding for AMD MicroBlaze/V soft cores executing from dual-port BRAM, with clock and reset control and support for firmware without a resource table. Introduce a generic Qualcomm PAS service with SCM and OP-TEE backends, and migrate the PAS, MSS, and WCNSS remoteproc drivers to it. Add Nord ADSP and CDSP support, Eliza CDSP support, Maili ADSP/CDSP bindings, and late-attach SoCCP support for Kaanapali, Hawi, Maili, and Glymur. Enable BAM-DMUX child devices for PAS modems and fix PAS memory protection, handover, shutdown, and resource lifetime handling. Harden remoteproc lifecycle handling by attaching asynchronously, stopping crashed processors, synchronizing crash work with removal, and forcing shutdown before device resources are released.

Arm:
* Add support for 'slot' based PMU events, paired with new UAPI that
compels the user to select a specific PMU implementation
* Lazy save/restore of vCPU state for pKVM, along with various fixes
and cleanups to the management of vCPU state between the untrusted
host and pKVM hypervisor
* Disable traps of EL1 registers for nested hypervisors when FEAT_NV2p1
is present, guaranteeing that EL2-specific register bits are stateful
in the EL1 counterpart
* Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the scope
of those instructions remains 'in host' (i.e. L1 kernel/userspace)
* Pile of fixes for the management of the VNCR pseudo-TLB, such as
under-invalidations and races with concurrent TLBIs on other vCPUs
* Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
runtime-patched constant, allowing the same data to be shared with
pKVM prior to dropping host privileges
* Considerable pile of LLM-assisted fixes around the shop but mostly in
the VGIC, our in-kernel generator of bugs (and sometimes interrupts)
LoongArch:
* Advertise already-supported capabilities.
* Some bug fixes about timer and MMIO.
* Some hardening about interrupt injection.
* Replace kvm_err() with kvm_pr_unimpl().
* Add FPU/LSX/LASX test cases for selftests.
RISC-V:
* Svadu/Zicfiss/Zicfilp FWFT support for Guest
* Use try_cmpxchg for IMSIC MRIF RMW
* More arch-specific tracepoints in KVM RISC-V
* Eager page splitting when enabling dirty logging
* Optimize hfence request handling for SMP Guests
* Improve dirty log clearing by skipping zero bits in mask
* Guard HFENCE range loops against overflow
* CPU PM notifiers in KVM RISC-V for non-retentive idle states
* Fix kernel-mode vector context save/restore for Guest
s390:
* Fixes for vfio-ap
* Fixes for the gmap rework
* Fixes for vsie
* AI triggered fixes all over
* diag9c tracing
* code move preparation for the additional arm64 support
* enable CONTEXT_ANALYSIS
x86:
* Perform spring cleaning on x86.{c,h} and asm/kvm_host.h, by adding regs.c
(the kvm_cache_regs.h => regs.h is already applied) and msrs.{c,h}, and moving
relevant code out of x86.c.
* Split kvm_mmu in three parts, respectively to describe the format of page
tables, walking the guest page tables and building the page tables. Always
use the same page table walker kvm->arch.gva_walk as the entry point to
convert a guest's virtual address, where the previous code used two
different kvm_mmu structs depending on whether the walk included nested
EPT/NPT or not. Make page fault vmexits reuse the permission checking
machinery that is used for guest page faults. This is both a cleanup
and a baby step towards supporting XS/XU memory permissions.
* Document some of the "fun" gotchas with the APIC base when creating IRQCHIPs
on x86.
* Remove a defunct masterclock update from kvm_xen_shared_info_init(). It
could result in incorrect kvmclock due to triggering an unnecessary
switch to/from masterclock mode.
* Skip Xen runstate time updates if time has effectively gone backwards, so
that the guest doesn't report 100% steal time for a very, very long time.
* Drop KVM's runtime updates of the Xen PV timing CPUID leaf, as KVM was
updating the wrong sub-leaf, and upstream KVM will soon provide all the
information needed by userspace to populate the CPUID field itself.
* Fix a bug where KVM would walk a newly created rmap without holding the rmap
lock (or mmu_lock) during aging.
* Fix a bug where aging TDP MMU SPTEs could clobber FROZEN SPTEs.
* Fix a variety of #DB priority bugs.
* Fix a class of races related to enabling Hyper-V emulation on a vCPU after
the vCPU is visible to the rest of KVM.
* Use static calls for nested virtualization ops.
* Move more KVM-internal code out of x86's kvm_host.h.
* Enumerate support for a variety of Zhaoxin instructions that don't require
explicit virtualization.
* Fix missing EFER validation bugs, including in the KVM_SET_SREGS* path.
* Harden kvm_vcpu_map() against double-mapping and thus leaking references.
* Misc fixes and cleanups, e.g. for largely benign syzkaller splats.
x86 (Intel):
* Zero a vCPU's entry in VMX's Posted Interrupt Descriptor table used for IPI
virtualization when the vCPU is freed, to fix a use-after-free where hardware
will write to a freed vCPU's PID.
* Service local TLB flushes on a failed nested VM-Enter to fix a bug where KVM
could miss a TLB on a future, successful VM-Enter with the same L2 VPID.
* Cap the maximum value shoved into the VMX Preemption Timer to workaround an
erratum that affects all existing Intel CPUs that support CPUID 0x15.
* Fix VPID virtualization bugs where KVM would fail to flush hardware TLBs.
* Harden the TDX "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion.
x86 (AMD):
* Forcefully invalidate SNP VMSA pages if their backing guest_memfd page is
zapped/invalidated, e.g. due to a PUNCH_HOLE in response to a Page-State
Change request.
* Remove a dying VM from the GA Log notifier list before the VM is actually
destroyed, to fix a potential use-after-free.
* While FOLL_WRITE was needed in the past to trigger CoW unsharing, nowadays
FOLL_LONGTERM does that already even without FOLL_WRITE, and in fact,
get_user_pages() actually disallows FOLL_WRITE together with FOLL_LONGTERM.
So don't pass FOLL_WRITE when registering encrypted memory regions, i.e. when
pinning SEV/SEV-ES guest memory, to fix a regression with file-backed memory
introduced by KVM's (correct) usage of long-term pins.

Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

Bootconfig updates for v7.3:
- bootconfig: Support build-time command line rendering for embedded bootconfig
. bootconfig: render descendant keys when xbc_snprint_cmdline() root has a
value. Fix xbc_snprint_cmdline() to render descendant keys when the root
has both a value and subkeys, and treats empty subtrees correctly.
. bootconfig: render embedded bootconfig as a kernel cmdline at build time.
Add build-time pipeline using tools/bootconfig -C to render the embedded
bootconfig "kernel" subtree into .init.rodata as a cmdline string.
. bootconfig: clean build-time tools/bootconfig from make clean.
. bootconfig: add xbc_prepend_embedded_cmdline() helper.
Add helper to prepend embedded bootconfig cmdline into boot_command_line
early before parse_early_param().
. x86/setup: prepend embedded bootconfig cmdline before parse_early_param.
Wire early prepend helper in x86 setup_arch() so early_param handlers see
values from the embedded bootconfig. (So this feature is currently x86 only)
. bootconfig: skip runtime kernel.* render once prepended early.
Avoid duplicating "kernel" keys in setup_boot_config().
. init/main.c: use bootconfig_cmdline_requested() for the runtime opt-in.
Refactor setup_boot_config() to share bootconfig_cmdline_requested().
. Documentation: bootconfig: document build-time cmdline rendering.
Document CONFIG_CMDLINE_FROM_BOOTCONFIG usage, requirements, and precedence.

This contains 52 commits with improvements to compression support,
metadata handling, error propagation, and filesystem robustness.
New feature:
- Add optional read support for Windows System Compression (WOF).
Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading WOF-compressed
files through the NTFS page-read path. This includes parsing
REPARSE_TAG_WOF, handling resident and non-resident WOF metadata and
compressed chunks, and adding kernel-side XPRESS 4K/8K/16K and LZX 32K
decompressors. The codecs use a common transparent compression interface
shared with LZNT1. WOF support is read-only and disabled unless
explicitly enabled.
Other changes:
- Harden malformed filesystem handling and error paths.
Add bounds and consistency checks for mapping pairs, run lengths, MFT
locations, update-sequence offsets, non-resident attributes, compressed
attributes, index roots, and bitmap scans. Prevent out-of-bounds accesses
in decompression, MFT allocation, and index conversion paths, clean up MFT
mappings and attribute search contexts on failure, and propagate attribute
and inode initialization errors correctly.
- Improve compressed-file I/O path.
Fix compressed writes on large-page and highmem systems, reuse compression
contexts and output workspaces, avoid unnecessary reads for full-unit
overwrites, and submit one bio per compressed write unit. Write replacement
data before publishing the new mapping, correctly handle zero-filled
compressed blocks, and fix initialized-size and folio state updates after
compressed writes.
- Synchronize resident reads with MFT record updates.
- Validate the final EA stream size before modifying existing data, rewrite
the stream safely when replacing entries, restore the previous state when
metadata updates fail, and remove the EA attribute pair when the last
entry is deleted.
- Apply Windows filename restrictions only when windows_names is enabled.
- Allow index roots to relocate to extent MFT records when the base record
lacks sufficient space.
- Move non-resident attribute payload data before shrinking its record.
- Correct resident-to-non-resident conversion when compression or sparse
flags are enabled.
- Prepare file allocation and initialized-size updates before buffered or
direct I/O submission, and use pagecache_isize_extended() when extending
the file size.
- Fix highmem and page/folio access in compressed I/O paths by using the
correct local mappings and page helpers.
- Apply per-file $LXMOD permissions instead of mount masks when available,
and prevent unprivileged writes to reserved $LX* attributes.
- Update the NTFS maintainer mailing list.
- Four small cleanups.

selftests/proc: make proc-maps-race work with READ_IMPLIES_EXEC
test_maps_tearing_from_split times out when READ_IMPLIES_EXEC is set.
This happens by default on pre-ARMv6 CPUs, which lack no-execute support.
split_vma() re-maps the first page with mod_info->prot | PROT_EXEC to make
it differ from its neighbours. With READ_IMPLIES_EXEC the original
mapping is already executable, so no split occurs and the test hangs
waiting for the modifier child.
Use PROT_NONE for the split mapping, which always differs from its
readable neighbours.

memcg: move LRU size accounting on reparenting instead of copying it
When a memory cgroup is offlined its LRU folios are reparented to the parent. lruvec_reparent_lru() splices the child's lists into the parent's and credits the parent with the child's per-zone lru_zone_size[], but never clears the child's copy, so the size is copied rather than moved. lru_gen_reparent_memcg() does the same for MGLRU. The parent is left correct, credited with exactly the folios it took over. The stale value sits on the child and nothing will correct it: folio->memcg_data now resolves to the parent, so every later update_lru_size() for those folios goes there. Dying cgroups are not freed immediately and mem_cgroup_iter() still walks them, so shrink_lruvec() keeps being called on them. get_scan_count() reads the phantom counter through lruvec_lru_size() and the scan loop then grinds through nr[] in SWAP_CLUSTER_MAX steps against an empty list, for as long as the dead cgroup lives. Under MGLRU the MGLRU scanner runs instead, but count_shadow_nodes() sums all of NR_LRU_LISTS through lruvec_lru_size() and over-budgets the shadow node limit just the same. On one 251 GiB host a sweep of every mz->lru_zone_size[] found 380 counters describing folios on no list at all: 124777314 pages, 476 GiB, 1.89x the machine's RAM, across 57 cgroups. All were on memcgs with CSS_DYING set and CSS_ONLINE clear, and parent/child pairs reported byte-identical sizes. LRU_UNEVICTABLE needs its size moved too. Its list is deliberately not spliced because lruvec_init() poisons the head - the unevictable LRU is imaginary and folios are never threaded on it - but the size is kept by lruvec_add_folio()/lruvec_del_folio() and those folios account to the parent from here on. This depends on commit |

maple_tree: catch race in mas_alloc_cyclic()
If mas_alloc_cyclic() is called during a low memory situation, it is
possible the lock may be dropped so reclaim can occur. There is a window
where some other task may allocate the same id and cause the mas_insert()
to fail with -EEXIST. In this scenario the function will return -EEXIST,
which is not expected.
Modifying the retry on mas_nomem() to re-search for a slot means that any
race with other writes will not matter as the lock will be held between
finding the index and writing the index.
Moving the flag logic avoids cases where the flag is modified on drop
lock/reacquire or when the write fails after clearing the flag.
No existing users are exposed to this issue.

maple_tree: micro optimisation of mas_wr_store_type()
Use three new local booleans instead of reading other structures. This has shown an increase of 0.62% on a 2048 entry tree of height 4.

maple_tree: optimise mas_wr_node_store() when not in rcu mode
Clearing the entire node on the stack is unnecessary since most of the node will be overwritten anyways. Just clear what isn't used after the data is in place. Benchmarking shows a speedup of 0.67% on a height 4 tree with 2048 entries. Link: https://lore.kernel.org/20260821192627.4085470-10-liam@infradead.org Signed-off-by: Liam R.

maple_tree: use prefetched value in mas_wr_store_type()
The slot contents exist in wr_mas->content, which has less overhead than reading the slot again. Link: https://lore.kernel.org/20260821192627.4085470-9-liam@infradead.org Signed-off-by: Liam R.

maple_tree: clarify comments on mas_nomem()
When an allocation completely fails, the return is false. If the allocation succeeds or partially succeeds, return true to indicate a retry of the operation. Note that since the lock may have been dropped, the operation is retried from the start - including potentially allocating more memory.
