mm: swap: check for stable address space before operating on the VMA (2025-09-28 11:51:34 -0700)
----------------------------------------------------------------
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.
