This update includes two minor fixes that have been siting on linux-next
for the past weeks.
- A patch from David removing the normalization function that we no
longer use.
- A patch from me fixing a parsing issue in the encoding version
argument passed by filesystems.

Capabilities update for 7.3
This branch contains just one trivial patch:
capability: remove non-kernel-doc comments
which corrects two comments to avoid kernel-doc warnings. It's available at
git@git.kernel.org/pub/scm/linux/kernel/git/sergeh/linux.git #caps-20260820

This contains a set of nine exfat fixes covering shared writable mappings,
entry error handling, allocation cleanup, FITRIM bounds, and locking:
- Fix valid_size extension over shared writable mappings by lazily
zeroing page-cache gaps and ensuring racing stores cannot be
overwritten or extend beyond valid_size.
- Clean up partially written directory entries on add-entry failure and
safely free new directory clusters.
- Free a newly allocated directory cluster when zeroing it fails.
- Write the destination entry before removing the source entry during
rename, preserving the source if the destination write fails.
- Keep FITRIM within the requested range, even when the free-space search
wraps around the allocation bitmap.
- Fix truncated FS_IOC_GETFSLABEL results by passing the destination
buffer size in bytes to the UTF-16-to-NLS conversion.
- Fix overflow in the cluster-to-dentry calculation, which could cause
readdir to stop early on large volumes.
- Replace the per-inode truncate_lock with inode_lock, using shared
locking in bmap to serialize against concurrent truncation.
- Update the exfat mailing list address in MAINTAINERS.

perf tools updates for v7.3
perf c2c:
- Add 'function view' in perf c2c report TUI (switched by pressing 'TAB'
in the cacheline view) to organize samples around functions rather than
cachelines in 3-level hierarchy:
Level 1: Read-side function (sorted by estimated Cycles %)
Level 2: Contending writer functions (sorted by Store count)
Level 3: Shared cacheline addresses
Users can navigate the entries and fold/unfold using 'e' key. An example
output would look like below:
Shared Data Functions Table (19 entries, sorted on Cycles %)
Cycles Store
% count Function / Contending function / Cacheline
----------------------------------------------------------------------
+ 35.67% 876 + [k] cpupri_set
+ 24.31% 424 + [k] pull_rt_task
- 16.53% 555 - [k] dequeue_pushable_task
145 - [k] pull_rt_task
145 0xff2d0082809da080
139 - [k] enqueue_pushable_task
70 0xff2d00a2071f9640
69 0xff2d0082809da000
python module support:
- Extend "perf" python module so that it can be fully functional. The goal
is to run scripts directly, not by 'perf script' command. This would give
better performance as well as more control to build standalone programs
with UI.
- Add LiveSession helper (perf_live.py) to enable live event collection
directly from Python using perf.evlist and perf.parse_events.
perf stat:
- Add --hide-zero-events option to suppress zero-count events.
- Reject conflicting --field-separator and --json-output options.
- Fix duplicate event output with --for-each-cgroup.
perf sched latency:
- Add -H/--histogram and --hist-mode (log|linear) options to show scheduler
wait latency histograms.
- Add --time option to filter analysis by time span in 'perf sched latency'.
ARM CoreSight:
- Synthesize callchains for instruction samples from CoreSight trace
using thread stack ('--itrace=g...').
- Support call indentation ('perf script -F +callindent') to display call
depth hierarchy on branch samples.
- Decode ETE (Embedded Trace Extension) exception packets.
Build system:
- Add 'make install-build-deps' target to install required packages.
- Parallelize JSON and metric pre-computation in jevents.py for faster builds.
Vendor event/metric updates:
- Add Intel Nova Lake events and update tables for existing models.
- Update AMD Zen 5 and Zen 6 core events.
- Update Arm64 Tegra410 metrics and PowerPC hcalls.
Internal changes and fixes:
- Harden trace-event and synthetic event parsing against corrupted data.
- Fix unwinding of multi-threaded processes in libdw unwinder.
- Fix memory leaks in various commands and python bindings.
- Speed up 'perf test' shell tests.

firewire updates for v7.3
This update includes error checks, a potential bug fix, and KUnit tests.
Sreeraj S Kurup addressed an error case when generating the contents of
the configuration ROM with parameters supplied by in-kernel
implementations such as unit drivers. Some error checks were added to
handle failures in this path.
Abdun Nihaal identified a potential memory leak when an invalid self-ID
sequence causes an error while building the internal node tree. KUnit
tests have been added to trigger this case. This memory leak has existed
since the first commit and has now been fixed.

Modules changes for 7.3-rc1
- Remove unnecessary module::args. Nowadays, no parameter-handling code points into the module::args buffer. The last user of module::args in xtensa/simdisk is updated and the data is then removed. - Add Rust support for boolean parameters. This will initially be used by the Rust null block driver. - Fix clearing the current charp parameter value when setting a new one fails due to an allocation failure. - Improve the debugging code for kmod (request_module()) duplicates. Fix a potential use-after-free when waiting on a duplicate request and make several general improvements to the code. - Fix the symbol size returned when looking up a data symbol through kallsyms. - The remaining changes are smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQFkBAABCABOFiEEIduBR9MnFA82q/jtumpXJwqY6poFAmqG/rIbFIAAAAAABAAO bWFudTIsMi41KzEuMTIsMiwyFBxwZXRyLnBhdmx1QHN1c2UuY29tAAoJELpqVycK mOqaur8H/i1kJq+zQfUB6/ijvX4yRGXezX0O30iLJ2N/imVsnMe6xP2eqqFIb2Be r5gnCc8P1WRJrDIe3uMsQBpoWIxEpCJ0F+S6JXiFEdht66taco8ivpP4hJWGHerj dCIf7RA3JOFave/7mN4UsrSXtl3HUyrMXplYuycE/5l/pYUY06qXmetgpA2aWywu jVpnCW9I7OO55Tf8tto2X4h6TbXP7ukCnojnadFz+N8JlG2hs45CQYSl1wEzKaFv okqPWCHTexcWySaEbqWWogbzvzIL6lr9C+nKMzYggMDYH7TxMwfscvo4pmTO/nOx +EO4PArCenf+7nsV2wKl2YLbnbzM1oA= =p/Yx -----END PGP SIGNATURE----- Merge tag 'modules-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux Pull module updates from Petr Pavlu: - Remove unnecessary module::args.

eCryptfs updates for 7.3-rc1
The set of eCryptfs changes for the 7.3-rc1 merge window consists of: - Hardening and fixes for maliciously crafted eCryptfs metadata in the lower encrypted file - Hardening and fixes for maliciously crafted userspace <-> kernel miscdev communications - Locking fixes for userspace <-> kernel miscdev communications - Fix to display encrypted filename related mount options - Clean up address_space_operations and reduce build dependencies by moving to filemap_dirty_folio() - Get rid of an unnecessary memory allocation in the inode update path - Kernel-doc formatting corrections The patches have all spent time in linux-next and they pass all tests in the ecryptfs-utils tree. I did manual validation of the miscdev fixes since we don't have test coverage for that feature. -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEKvuQkp28KvPJn/fVfL7QslYSS/0FAmqHmJURHGNvZGVAdHlo aWNrcy5jb20ACgkQfL7QslYSS/3N9Q/+JFdmV0MU5oxbYMorJIfdR6cpRK28OvXN qaLX4wnQO3hvzILQ+GqX9KuFuqrIos3bbJpS5kGFjt2YpmVwFZwdcSQSLrHzxILA 6vexECAUmfJyVJqaraGzReZJYJfn3NBHrO8qizNzeuOGWqmvhSNIV5wi7T2yVaav LspVIjUtxaqHG4Sm2ZkW4Mm9T4wSYWl3QasyyV2Nir+KCdFekQS8GNx7LnkXm2L3 iqiEvijfNyVR4IVNnrzwdozIOqBqP5At4y1Uj+w4N7mjXzVEg158QV7nC1ndttGx z4HuomgQI0Xo61WYmQgb0omC7FIlFD422+nrrK3ZKFz881e1ozKd7hGa3r1gSeP9 lZma2GsQNYojYEWc/TgkyP/U3eUKVYeqmsWIyQjSKe1a1pmITgz8fMUiyegdVOSC Y20AH3fY0f8xRcUGv6BXeUYw4E5bED5Bh8/CgzcUpi5Vc3K3E/yxofrbZAuGJFSl KJ8Mfq9nsdVvuCWga2izglVecMWCjVuqM29yALh3nhmQXwuw6iJCF3Ob27kln97J GLmewNUj1tkhixzoGkx16VxEzrRR+GQoSnpmxXFvAke7EfHYkEQxlKF84phSsYR4 0hhP7EzhkgrNVXB2HB88LPTIBhO4fqoqCKPca33ZC4vMcDGuC4kJvXz/BiaY9CPp Y58PFrWNGjc= =LCDJ -----END PGP SIGNATURE----- Merge tag 'ecryptfs-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs Pull eCryptfs updates from Tyler Hicks: - Hardening and fixes for maliciously crafted eCryptfs metadata in the lower encrypted file - Hardening and fixes for maliciously crafted userspace <-> kernel miscdev communications - Locking fixes for userspace <-> kernel miscdev communications - Fix to display encrypted filename related mount options - Clean up address_space_operations and reduce build dependencies by moving to filemap_dirty_folio() - Get rid of an unnecessary memory allocation in the inode update path - Kernel-doc formatting corrections * tag 'ecryptfs-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: ecryptfs: ecryptfs_kernel.h: clean up kernel-doc comments ecryptfs: use filemap_dirty_folio for address space operations ecryptfs: avoid heap allocation for inode size write ecryptfs: show filename encryption options eCryptfs: bound the packet-length peek to the user buffer ecryptfs: reject too-small tag 70 packets ecryptfs: fix tag 11 packet exact-fit size check ecryptfs: pass packet set buffer size to parser ecryptfs: hold msg ctx list lock when cleaning daemon queue ecryptfs: release message context on send failure ecryptfs: reject oversized encrypted_key_size in parse_tag_3_packet |

SCSI misc on 20260821
One new driver: leapraid (similar to mpi3mr but OK'd by Broadcom).

drm/xe: Don't hand out the flat CCS storage as usable VRAM
get_flat_ccs_offset() reads the base of the flat CCS storage from the
hardware, scales it by the number of enabled L3 nodes, and rounds the
result up to 128K. Everything below that offset is then handed to the
VRAM allocator as usable memory.
Rounding a limit that means "usable memory ends here" upwards publishes
whatever lies between the real base and the rounded one as free memory,
and that memory belongs to the compression hardware. The scaled value
has no reason to be 128K aligned, and on a Battlemage G21 with 16 GiB it
is not:
flat CCS base: raw 0x3fafff800, rounded 0x3fb000000
so the last 2 KiB of page 0x3fafff000 is CCS storage, in the allocator's
pool. Whatever is allocated there gets that tail overwritten by the
compression hardware, which needs no page-table entry, no buffer object
and no GPU submission to do it, and does it before userspace exists.
On this machine a Mesa VM's level-3 page table landed on that page on
every cold boot. It lost the entry covering the compositor's
batch-buffer heap, so the compositor's first submission faulted fetching
its batch and gdm restarted it forever: a black screen on an otherwise
working machine. Restarting gdm cleared it because the next VM's page
tables were allocated somewhere else.
Round down instead, to the page size the allocator works in. On this
machine that excludes exactly one page.
Reading the reserved page afterwards shows what had been writing it:
[369] 0xcccc000000000000
[371] 0xcc77000000000000
[373] 0xcccc000000000000
[375] 0xcc77000000000000
compression metadata, two bytes per sixteen, sitting where the driver
used to hand out memory.
The assertion that should have caught this compares the offset against
GSMBASE - ccs_size for equality. That value is 128K aligned, so it
agrees with the rounded-up offset precisely when the base is not
aligned - the check cannot fail in the case it exists to catch, and is
compiled out unless CONFIG_DRM_XE_DEBUG is set. Replace it with one
that can fail: CCS storage must not run into GSM.
[ And this was a debug session from hell, enormously helped by an AI
doing much of the grunt-work.
I'd like to call it my tireless helper, but the AI several times
stated flat out that this was impossible and unsolvable and that we
should just write a report about it.
I suspect those things have been trained by people who may not be
quite as stubborn as I am.
But while the AI was ready to give up several times, it did keep
adding debug code and analyzing it faithfully when I pushed. So credit
where credit is due and I let the AI write the commit message above.
This is basically a one-liner fixing a bogus "round_up()" to a
"round_down()", but there were 24 patches adding more and more debug
information to this, and 18 kernel boot to finally narrow it down to
this. - Linus ]

Summary of patch series in this merge:
- The 2 patch series "mm: drop "sub" prefix from various places" from
Dev Jain implements some page->folio conversion and a naming cleanup.
- The 2 patch series "mm/kasan: remove redundant initialization for
kasan_flag_write_only" from Igor Putko provides some KASAN cleanup work.
- The 2 patch series "mm/filemap: reduce unnecessary xarray lookups"
from Chi Zhiling provides a small speedup in the pagecaache read code.
- The 4 patch series "mm/percpu: Fix possible NOFS/NOIO reclaim
recursion" from Kaitao Cheng improves a few things in the vmalloc code -
mainly the avoidance of GFP_KERNEL allocations when the caller asked for
GFP_NOFS or GFP_NOIO.
- The 3 patch series "mm/kmemleak: avoid soft lockup when scanning task
stacks" from Breno Leitao avoids a soft lockup watchdog trigger from the
kmemleak scanning code in extreme situations.
- The 6 patch series "mm/page_owner: misc cleanups" from Ye Liu is a
collection of unrelated cleanups to the page_owner code. For some
reason lots of people have been working on the page_owner code this
cycle.
- The 4 patch series "mm: convert to walk_page_range_vma() to eliminate
find_vma()" from Kefeng Wang simplifies and accelerates the page walking
library function.
- The 3 patch series "mm/migrate: preparatory cleanups for batch copy
and offload" from Shivank Garg implements cleanups in the migration
code.
- The 4 patch series "mm/page_owner: add per-fd filter infrastructure
for print_mode and NUMA filtering" from Zhen Ni provides per-fd
filtering to page_owner in order to reduce the sometimes vast amount of
output it can produce.
- The 19 patch series "mm: Refactor bootmem gigantic hugepage
allocation" from Muchun Song is a "set of fixes and preparatory cleanups
around bootmem HugeTLB handling, sparse initialization ordering, and
related vmemmap setup".

need for complex and error-prone caller-side cleanup code.
- The 5 patch series "Keep tail page private zero at free and folio
split" from Zi Yan adds checks to ensure tail_page->private is zero when
freeing compound or high-order pages and when promoting tail pages
during large folio splits. By validating these fields at free and split
time, it allows the removal of redundant private field clearing inside
prep_compound_tail().
- The 4 patch series "mm: drop redundant lru_add_drain in anon folio
reuse paths" from Barry Song eliminates redundant lru_add_drain() calls
in wp_can_reuse_anon_folio() and do_swap_page() to reduce LRU lock

monitoring" from SJ Park introduces attribute-weighted region management
in DAMON, allowing users to prioritize specific data attributes (such as
page sizes or cgroups) over or instead of access monitoring.
By assigning weights to attribute probes, DAMON can completely disable
access tracking and adjust monitoring regions based on weighted
probe-hit counters to optimize monitoring quality for attribute-focused
workloads.
- The 8 patch series "mm/hmm: Add mmap lock-drop support for
userfaultfd-backed mappings" from Stanislav Kinsburskii extends
hmm_range_fault() to support userfaultfd-backed regions by allowing the
mmap lock to be dropped during fault handling via a new
hmm_range_fault_locked() helper.
By accepting a locked pointer and signaling retry status when lock
release occurs, it enables page fault resolution in userfaultfd regions
while preserving backward compatibility for existing callers.
- The 33 patch series "mm: make VMA page offset handling more
consistent" from Lorenzo Stoakes cleans up and standardizes how
vma->vm_pgoff is accessed and manipulated across file-backed and
anonymous mappings in the kernel.
It introduces dedicated helper functions such as vma_start_pgoff(),
vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while renaming
rmap interval tree helpers to better reflect their functionality.
These changes establish a cleaner foundation for future work that will
unify virtual page offset indexing for all anonymous and CoW'd folios.
- The 3 patch series "mm: handle device-private PMDs in walk callbacks"
from Usama Arif addresses kernel panics and state corruption caused by
MM walk callbacks reaching non-present device-private PMD swap entries

recognize device-private PMDs instead of assuming a present THP or a
standard migration entry.
- The 5 patch series "mm/rmap: Refactor try_to_unmap_one" from Dev Jain
refactors try_to_unmap_one by modularizing Hugetlb, anonymous-lazyfree,
and anonymous-swapbacked logic into dedicated functions, laying the
structural groundwork for batched anonymous large folio unmapping.
- The 4 patch series "Docs/ABI/damon: sysfs ABI document fixes and
additions" from Song Hu fixes typos and fills in missing entries in the
DAMON sysfs ABI document.
- The 10 patch series "dax/kmem: atomic whole-device hotplug via sysfs"
from Gregory Price introduces an atomic sysfs state attribute and
supporting DAX/MM infrastructure to prevent userland races when
offlining and removing entire memory regions.
By adding an unplugged state alongside standard online modes, it
enables whole-device atomic hotplug control while preserving backward
compatibility.
- The 13 patch series "mm: convert more vm_flags_t users to vma_flags_t"
from Lorenzo Stoakes continues transitioning the kernel from the
deprecated vm_flags_t type to vma_flags_t across core memory management
infrastructure.
It replaces legacy type usage in core functions such as do_mmap(),
unmapped area allocation, mm->def_vma_flags, and VMA operations like
mlock, mprotect, and mremap.
- The 2 patch series "Two small patches to clean up mm/mm_slot.h" from
xu xin refactors mm_slot.h by introducing mm_slot_remove() to unify
duplicate slot deletion sequences in khugepaged and KSM. It also adds
code documentation explaining why mm_slot_lookup and mm_slot_insert must
remain as preprocessor macros rather than static inline functions.
- The 10 patch series "mm/damon/core: hide core-private struct fields"
from SJ Park cleans up DAMON core structures by consistently marking
internal-only fields with private: comment tags to prevent improper
direct access from outer layers.
It enforces encapsulation across core structures including
damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to
interact through approved access APIs instead of exposing raw struct
members.
- The 6 patch series "mm/damon: unurgent fixes for infinite loop, NULL
de-ref and races" from SJ Park addresses potential infinite loops, NULL
dereferences, and race conditions identified in DAMON.
It fixes an infinite loop triggered by extreme user configurations, a
NULL pointer dereference within unit tests and minor monitoring
accuracy degradation caused by subtle runtime races.
- The 2 patch series "mm/page_alloc: fixes for free_pages_nolock() on
RT/UP" from Brendan Jackman fixes an NMI safety flaw in
__free_frozen_pages() where freeing pages on non-SMP or PREEMPT_RT
kernels can bypass can_spin_trylock() checks via non-PCP or isolated
migration paths.
It also resolves potential kernel crashes and privilege escalation
risks triggered when BPF tracing runs in NMI context alongside memory
hotplug or large allocation frees.
- The 4 patch series "mm/page_alloc: couple of followups for recent
cleanups" from Brendan Jackman cleans up and updates page allocator
nomenclature, documentation, and debug assertions.
It aligns internal FPI_ flags with the public "nolock" naming
convention, removes outdated internal implementation details from
high-level page allocator comments, and eliminates obsolete VM_BUG_ON()
assertions in allocation paths.
- The 3 patch series "mm/mseal: further cleanups" from Lorenzo Stoakes
refactors and simplifies the mseal implementation by clarifying API
boundaries and removing unnecessary code complexity.
It replaces generic do_mseal() usage outside the syscall with a
dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO, eliminates
mm_struct parameters to enforce that sealing applies only to
current->mm, and streamlines overall logic and comments with no
functional changes intended.
- The 4 patch series "mm/vmscan: fix swappiness=max and clean up
per-node proactive reclaim" from Ridong Chen resolves reclaim behavior
bugs and cleans up function parameters across memory reclaim paths.
It fixes swappiness=max in both standard reclaim and MGLRU so
unswappable anonymous memory no longer falls back to evicting page
cache, ensures reclaim_store() returns accurate error codes instead of
collapsing all failures into -EAGAIN, and removes the obsolete gfp_mask
parameter from __node_reclaim().
- The 6 patch series "mm: mincore: misc cleanups" from Kefeng Wang
cleans up and simplifies the mincore code. Most importantly, it removes
the historical special behavior that always reports VM_PFNMAP pages as
non-resident.
- The 2 patch series "mm/huge_memory: drop dead split helper variants"
from Kiryl Shutsemau implements two trivial cleanups in the folio split
API.
- The 7 patch series "mm/damon: fix uninitialized DAMOS field and kunit
exec expectation bugs" from SJ Park resolves minor operational and
testing bugs in DAMON identified by Sashiko. It initializes the
damos->last_applied field to prevent occasional efficiency degradation
and fixes invalid memory accesses in DAMON KUnit tests during test
failure handling.
- The 3 patch series "cleanup for stable_page_flags()" from Jinjiang Tu
cleans up and refactors stable_page_flags() used by /proc/kpageflags
without altering functionality.
It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag
bits, converts folio-specific flag checks to standard folio_test_*()
helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling.
- The 3 patch series "Batch unmap of uffd-wp file folios" from Dev Jain
extends batched folio unmapping support to file folios within
userfaultfd write-protect (uffd-wp) VMAs by adding batching capabilities
to pte_install_uffd_wp_if_needed().
This removes special-case restrictions on uffd-wp VMAs in
try_to_unmap_one(), significantly simplifying the function's control
flow and complexity.
- The 3 patch series "mm/early_ioremap: clarify and clean up
early_ioremap_reset()" from Sang-Heon Jeon clarifies and cleans up the
architecture-specific usage of __late_set_fixmap() and
__late_clear_fixmap() after early_ioremap_reset().
It adds explicit documentation regarding when early_ioremap_reset()
must be called and removes redundant macro definitions and reset calls
in the RISC-V and ARM64 architectures.
- The 4 patch series "mm: fix reclaim storms in defrag_mode" from
Johannes Weiner addresses severe performance regressions, swap storms,
and spurious OOMs caused by vm.defrag_mode=1 under high memory pressure
in Meta production.
It updates the page allocator slowpath so non-movable allocation
requests actively trigger direct reclaim and direct compaction at
pageblock_order scale, allowing them to claim whole pageblocks rather
than spinning unproductively.
- The 2 patch series "zram: lockmap tweaks" from Sebastian Siewior
optimizes and fixes lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolating lock classes across multiple instances.
It reduces memory overhead by replacing per-entry lockdep_map instances
with a single map per struct zram, and assigns a dynamic lock_class_key
to each instance to prevent false deadlock reports when different zram
devices are backed by distinct filesystems.

functionality.
These changes establish a cleaner foundation for future work that
will unify virtual page offset indexing for all anonymous and CoW'd
folios.
- "mm: handle device-private PMDs in walk callbacks" (Usama Arif)
Address kernel panics and state corruption caused by MM walk
callbacks reaching non-present device-private PMD swap entries
created during HMM migrations
It ensures that functions which acquire pmd_trans_huge_lock()
properly recognize device-private PMDs instead of assuming a present
THP or a standard migration entry.
- "mm/rmap: Refactor try_to_unmap_one" (Dev Jain)
Refactor try_to_unmap_one by modularizing Hugetlb,
anonymous-lazyfree, and anonymous-swapbacked logic into dedicated
functions, laying the structural groundwork for batched anonymous
large folio unmapping.
- "Docs/ABI/damon: sysfs ABI document fixes and additions" (Song Hu)
Fix typos and fills in missing entries in the DAMON sysfs ABI
document
- "dax/kmem: atomic whole-device hotplug via sysfs" (Gregory Price)
Introduce an atomic sysfs state attribute and supporting DAX/MM
infrastructure to prevent userland races when offlining and removing
entire memory regions
By adding an unplugged state alongside standard online modes, it
enables whole-device atomic hotplug control while preserving backward
compatibility.
- "mm: convert more vm_flags_t users to vma_flags_t" (Lorenzo Stoakes)
Continue transitioning the kernel from the deprecated vm_flags_t type
to vma_flags_t across core memory management infrastructure.
It replaces legacy type usage in core functions such as do_mmap(),
unmapped area allocation, mm->def_vma_flags, and VMA operations like
mlock, mprotect, and mremap.
- "Two small patches to clean up mm/mm_slot.h" (xu xin)
Refactor mm_slot.h by introducing mm_slot_remove() to unify duplicate
slot deletion sequences in khugepaged and KSM. It also adds code
documentation explaining why mm_slot_lookup and mm_slot_insert must
remain as preprocessor macros rather than static inline functions.
- "mm/damon/core: hide core-private struct fields" (SJ Park)
Clean up DAMON core structures by consistently marking internal-only
fields with private: comment tags to prevent improper direct access
from outer layers.
It enforces encapsulation across core structures including
damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to
interact through approved access APIs instead of exposing raw struct
members.
- "mm/damon: unurgent fixes for infinite loop, NULL de-ref and races"
(SJ Park)
Address potential infinite loops, NULL dereferences, and race
conditions identified in DAMON
It fixes an infinite loop triggered by extreme user configurations, a
NULL pointer dereference within unit tests and minor monitoring
accuracy degradation caused by subtle runtime races.
- "mm/page_alloc: fixes for free_pages_nolock() on RT/UP" (Brendan
Jackman)
Fix an NMI safety flaw in __free_frozen_pages() where freeing pages
on non-SMP or PREEMPT_RT kernels can bypass can_spin_trylock() checks
via non-PCP or isolated migration paths.
It also resolves potential kernel crashes and privilege escalation
risks triggered when BPF tracing runs in NMI context alongside memory
hotplug or large allocation frees.
- "mm/page_alloc: couple of followups for recent cleanups" (Brendan
Jackman)
Clean up and update page allocator nomenclature, documentation, and
debug assertions.
It aligns internal FPI_ flags with the public "nolock" naming
convention, removes outdated internal implementation details from
high-level page allocator comments, and eliminates obsolete
VM_BUG_ON() assertions in allocation paths.
- "mm/mseal: further cleanups" (Lorenzo Stoakes)
Refactor and simplify the mseal implementation by clarifying API
boundaries and removing unnecessary code complexity.
It replaces generic do_mseal() usage outside the syscall with a
dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO,
eliminates mm_struct parameters to enforce that sealing applies only
to current->mm, and streamlines overall logic and comments with no
functional changes intended.
- "mm/vmscan: fix swappiness=max and clean up per-node proactive
reclaim" (Ridong Chen)
Resolve reclaim behavior bugs and clean up function parameters across
memory reclaim paths
It fixes swappiness=max in both standard reclaim and MGLRU so
unswappable anonymous memory no longer falls back to evicting page
cache, ensures reclaim_store() returns accurate error codes instead
of collapsing all failures into -EAGAIN, and removes the obsolete
gfp_mask parameter from __node_reclaim().
- "mm: mincore: misc cleanups" (Kefeng Wang)
Clean up and simplifies the mincore code. Most importantly, it
removes the historical special behavior that always reports VM_PFNMAP
pages as non-resident.
- "mm/huge_memory: drop dead split helper variants" (Kiryl Shutsemau)
Two trivial cleanups in the folio split API
- "mm/damon: fix uninitialized DAMOS field and kunit exec expectation
bugs" (SJ Park)
Resolve minor operational and testing bugs in DAMON identified by
Sashiko. It initializes the damos->last_applied field to prevent
occasional efficiency degradation and fixes invalid memory accesses
in DAMON KUnit tests during test failure handling.
- "cleanup for stable_page_flags()" (Jinjiang Tu)
Clean up and refactor stable_page_flags() used by /proc/kpageflags
without altering functionality.
It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag
bits, converts folio-specific flag checks to standard folio_test_*()
helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling.
- "Batch unmap of uffd-wp file folios" (Dev Jain)
Extend batched folio unmapping support to file folios within
userfaultfd write-protect (uffd-wp) VMAs by adding batching
capabilities to pte_install_uffd_wp_if_needed().
This removes special-case restrictions on uffd-wp VMAs in
try_to_unmap_one(), significantly simplifying the function's control
flow and complexity.
- "mm/early_ioremap: clarify and clean up early_ioremap_reset()"
(Sang-Heon Jeon)
Clarify and clean up the architecture-specific usage of
__late_set_fixmap() and __late_clear_fixmap() after
early_ioremap_reset()
It adds explicit documentation regarding when early_ioremap_reset()
must be called and removes redundant macro definitions and reset
calls in the RISC-V and ARM64 architectures.
- "mm: fix reclaim storms in defrag_mode" (Johannes Weiner)
Address severe performance regressions, swap storms, and spurious
OOMs caused by vm.defrag_mode=1 under high memory pressure in Meta
production
It updates the page allocator slowpath so non-movable allocation
requests actively trigger direct reclaim and direct compaction at
pageblock_order scale, allowing them to claim whole pageblocks rather
than spinning unproductively.
- "zram: lockmap tweaks" (Sebastian Siewior)
Optimize and fix lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolate lock classes across multiple instances
This reduces memory overhead by replacing per-entry lockdep_map
instances with a single map per struct zram, and assigns a dynamic
lock_class_key to each instance to prevent false deadlock reports
when different zram devices are backed by distinct filesystems.

VFIO updates for v7.3-rc1
- Add nv_falcon vfio selftest driver. The Falcon is a general-purpose
microcontroller embedded within NVIDIA GPUs, presenting a relatively
simple DMA programming interface. This adds another selftest target
for vfio-pci with real DMA transfers. (Rubin Du, Alex Williamson)
- Add allocation assertion helpers to vfio selftests and use them to
avoid variable length arrays and the compiler errors they generate.
(Alex Mastro)
- Fix use-after-free hazard where an init path error in MSI support
leaves a stray pointer that can later be reused or double-freed.
(Xiang Mei)
- Fix previous refactor of PCI BAR mappings to honor non_mappable_bars
flag, which otherwise generates a warning when trying to pci_iomap()
a 256TiB BAR on ISM devices on s390. (Farhan Ali)
- Add igb vfio selftest driver. Like nv_falcon, this provides another
target for DMA testing with vfio selftests, but importantly this
driver supports both physical 82576 NICs and the emulation model in
QEMU. This therefore enables a vfio selftest vector with no physical
hardware requirements. (Josh Hilke, Alex Williamson)
- Mark selftest fixture objects __maybe_unused to accommodate builds
with clang -Wunused-but-set-global. (David Matlack)
- Add error recovery for vfio-pci devices on s390x. This expands
devices which expose the existing error eventfd and introduces a
device feature for reporting firmware defined error state
information to the user, allowing recovery through hypervisor
channels. (Farhan Ali)

(e.g., (STRUCT)PARAM->MEMBER) to kprobes, uprobes, and fprobes on
function entry and return.
. Nested typecasts: Added support for chaining and nesting typecasts up
to 3 levels, including casting registers and stack variables.
. Field specifier option: Added (STRUCT,FIELD) syntax to emulate
container_of(), allowing retrieval of parent structures from member
pointers.
. $current variable support: Introduced $current special variable to
access the running task_struct via BTF dereferencing.
. Per-CPU variable access: Added this_cpu_read() and this_cpu_ptr()
fetcharg methods to trace CPU-local data safely.
. Fetcharg bytecode dumper: Added CONFIG_PROBE_EVENTS_DUMP_FETCHARG to
dump the compiled fetcharg bytecode instructions as comments in
dynamic_events.
. Extended symbol name handling: Removed the MAX_COMMON_HEAD_LEN limit
and extended MAX_ARGSTR_LEN to 256 bytes, enabling probing of long
symbols, mangled Rust symbols and complex BTF expressions.
. eprobe variable syntax: Allowed eprobes to reference event fields
directly without requiring a '$' prefix.
. Cleanup unused parameters, redundant codes, duplicate macros and
pointer arithmetic.
. Use a ternary operator for simplifying fetch_type_from_btf_type().

fbdev: atafb: Add support for SuperVidel's SuperBlitter
The SuperVidel graphics FPGA includes a hardware blitter (bit block transfer engine) operating within the SuperVidel DDR2 video RAM. Two versions of this blitter exist. Later versions (>= 9) of the SuperVidel firmware support an asynchronous command FIFO, older versions must be polled for command completion. Add hardware-accelerated copyarea, fillrect and imageblit fb operations (falling back to the non-accelerated versions for anything that exceeds blitter capabilities).

fbdev: atafb: Give atafb proper parent
The atafb fb device registers no parent, causing a missing symlink (/sys/class/graphics/fb0/device). Xorg fbdevhw driver looks for that symlink when scanning for devices, so add a parent node for atafb. The proper way to do that is use of framebuffer_alloc(), which requries refactoring atafb to move from static fb_info to allocation of fb_info by framebuffer_alloc(). About the only location where a fb_info pointer cannot be passed is monspec setup in atafb_setup(). Store static monspecs there and copy into place after framebuffer_alloc(). Pass fb_info everywhere it's needed (detect, decode_var and do_fb_set_var functions), and remove the static fb_info struct.

fbdev: omapfb: panel-dsi-cm: initialize lock before registering display
dsicm_probe() registers the display before initializing ddata->lock.
Once omapdss_register_display() publishes the display, another consumer
can reach a dsicm callback that takes this mutex while it is still
uninitialized.
Initialize the mutex before registering the display so the published
callbacks always see a valid lock.

Eliminate the single-use file-scope variable `viafb_name` and pass the "Via" string literal directly to strcpy().

Pull io_uring update from Jens Axboe:
"On top of the usual cleanups and fixes, the bigger items in here are:
- zcrx work, most of it centered around adding dynamic area
provisioning, plus a bunch of prep and cleanups leading up to it:
scale refilling with large pages, coalesce same-niov RQEs on
refill, separate the RQ head/tail cache lines and cache the RQ
tail, and rework the area creation locking.
- Fix the futex inflight accounting so that only private futex waits
are marked inflight, and don't mark wake requests as inflight at
all.
- Drop the custom iov copy in the buffer select prep and msg header
copy paths, using the generic helpers instead.
- Fix a folio size overflow in io_vec_fill_bvec(), and account the
pages a compound region really uses in the memmap path.
- Fix an iovec leak in uring_cmd when the async cmd isn't recycled,
skip the blocking task work for io_uring_cmd_issue_blocking(), and
don't skip completion for a synchronous multishot cmd
- Defer eventfd signaling when queued from a wakeup handler

Pull btrfs updates from David Sterba:
"This is the summer edition of btrfs changes, smaller than usual. Yet,
there are performance improvements in various areas or for specific
workloads and some notable changes like removing space cache v1 code
or mount option reduction.
User visible changes:
- free space v1 disabled by default; the v2 (free space tree) is mkfs
default since 5.15, filesystems with v1 still work but could be
slightly slower due to lack of block group caching
- mount option 'rescue=usebackuproot' requires read-only mount, it's
too risky to allow writable mount
- remove standalone mount option 'usebackuproot', deprecated in 5.9
- preserve constraints of NODATASUM and NODATACOW when chattr and
mount options may change the attributes
- remove arbitrary limitation of 4KiB for page size when allowing
block sizes smaller than page
- print messages when pinned block groups affect swap activation
Performance improvements:
- use iomap bounce buffer for direct io instead of a fall back to
buffered io; past correctness vs speed trade-offs dropped
performance to ~50% of theoretical maximum, now it's ~95%,
effectively doubled
- replace xarray with local LRU list for tracking inhibited
extent buffers, restored performance to pre-inhibition state
(relatively ~3x)
- remove unnecessary 1 jiffy delay in "non-SSD" mode with multiple
logging tasks, decrease latency, throughput increased ~5x on sample
workload
- skip hole detection during full fsync for files without holes
and lots of extents, reduce run time ~5x on sample workload
(microsecond ranges)
- reduce locking around extent readahead so it does not slow down
other tasks using an overlapping range
- enhance extent buffer allocation modes to allow NOWAIT semantics
in some cases
Notable fixes:
- write-protect folios during writeback, prevent concurrent mmap
and compress/checksumming/etc undesired interactions
- in zoned mode, handle transient overcommit full instead of going
read-only
- fix possible deadlock between defragmentation and delayed
allocation reservations
- handle remaining iputs at umount time
- fix lockdep warning between device scan locking and log mutex
- add workaround for degenerate RAID56 device count modes (2 and 3)
not supported by the parity calculation library
- restore check that subvolume is not read-only when changing ACLs
- retry reading verity data colliding with up-to-date status changes
Core:
- simplify raid56 stripe handling by using contiguous virtual
allocations
- in zoned mode, fix various metadata write issues in writeback or
unmount
- space reservation fixes
- remove unused data structure members
- more auto-freeing conversions
- error pointer values are printed using %pe format"

NFSD 7.3 Release Notes
Jeff Layton contributed CB_NOTIFY support to NFSD's NFSv4.1
directory delegations. The server used to recall a delegation as
soon as the directory changed. NFSD now watches delegated
directories through fsnotify and reports adds, removes, renames,
and directory attribute changes, carrying the filehandle and
attributes of the affected entry, so clients can keep their
caches. Some of the NOTIFY4 flags come from RFC 8881bis.
Jeff Layton also continued the netlink work that started in v7.2.
A new server-stats-get operation reports what /proc/net/rpc/nfsd
publishes, plus NFSv4 callback counts, and SUNRPC now keeps its
per-procedure call counts per network namespace, so a container
sees its own numbers. nfsstat reads all of this over netlink, with
a procfs fallback for older kernels.
SUNRPC's service thread pool mode selection is gone. Pernode is
the right choice on any host we run today, so the auto, global,
and percpu modes have been removed. A single-node host still gets
one pool. A multi-NUMA host now gets a pool per node.
sunrpc.pool_mode accepts the old names but no longer selects
anything.
The rest is bug fixes, clean-ups, and small optimizations: an
async COPY offload rework from Jeff Layton, more use-after-free
fixes in the NFSv4 state revocation paths, percpu counter
contention removed from the reply cache and IO accounting, and a
long list of hardening fixes from Chris Mason. Sincere thanks to
all contributors, reviewers, testers, and bug reporters who
participated in the v7.3 NFSD development cycle.

Fixed:
slab-out-of-bounds write in ni_create_attr_list()
out-of-bounds read of INDEX_ROOT in reparse/objid init
boundary check in ntfs_dir_count()
info-leak in ntfs_rename()
lseek EINVAL on sparse/compressed files with 64-bit clusters
info-leak on partial LZNT decompress in ni_read_frame()
