Patchsets in this merge:
- The 2 patch series "selftests/mm: clean up build output and verbosity"
from Li Wang removes some noise from the MM selftests build out.
- The 3 patch series "mm: Free contiguous order-0 pages efficiently"
from Ryan Roberts speeds up the freeing of a batch of 0-order pages by
first scanning them for coalescing opportunities. This is applicable to
vfree() and to the releasing of frozen pages.
- The 11 patch series "mm/damon: introduce DAMOS failed region quota
charge ratio" from SeongJae Park addresses a DAMOS usability issue: The
DAMOS quota often exhausts prematurely because it charges for all memory
attempted, causing slow and inconsistent performance when actions fail
on unreclaimable memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing
- The 8 patch series "selftests/cgroup: improve zswap tests robustness
and support large page sizes" from Li Wang fixes various spurious
failures and improves the overall robustness of the cgroup zswap
selftests.
- The 3 patch series "fix MAP_DROPPABLE not supported errno" from
Anthony Yznaga fixes an issue in the mlock selftests on arm32.
- The 2 patch series "mm: huge_memory: clean up defrag sysfs with
shared" from Breno Leitao does some maintenance work in the huge_memory
code.
- The 3 patch series "treewide: fixup gfp_t printks" from Brendan
Jackman uses the special vprintf() gfp_t conversion in various places.
- The 6 patch series "mm: Fix vmemmap optimization accounting and
initialization" from Muchun Song fixes several bugs in the vmemmap
optimization, mainly around incorrect page accounting and memmap
initialization in the DAX and memory hotplug paths. It also fixes
pageblock migratetype initialization and struct page initialization for
ZONE_DEVICE compound pages.
- The 4 patch series "mm/damon: repost non-hotfix reviewed patches in
damon/next tree" from is a sprinkle of unrelated minor bugfixes for
DAMON.
- The 3 patch series "mm: remove page_mapped()" from David Hildenbrand
remove this function from the tree, replacing it with folio_mapped().
- The 10 patch series "mm/damon: let DAMON be paused and resumed" from
SeongJae Park permits DAMON to be paused and resumed without losing its
current state.
- The 3 patch series "kasan: hw_tags: Disable tagging for stack and
page-tables" from Muhammad Usama Anjum simplifies and speeds up kasan by
removing its ineffective tagging of stacks and page tables.
- The 7 patch series "mm/damon/reclaim,lru_sort: monitor all system rams
by default" from SeongJae Park simplifies deployment on diverse hardware
like NUMA systems by updating DAMON_RECLAIM and DAMON_LRU_SORT to
automatically monitor the physical address range covering all System RAM
areas by default, replacing the overly restrictive behavior that only
targeted the single largest memory block to save on negligible overhead.
- The 2 patch series "mm/damon/sysfs: document filters/ directory as
deprecated" from SeongJae Park updates some DAMON docs.
- The 8 patch series "mm: use spinlock guards for zone lock" from Dmitry
Ilvokhin switches zone->lock handling over to using the guard()
mechanisms.
- The 2 patch series "mm/filemap: tighten mmap_miss hit accounting" from
fujunjie fixes a flaw where the mmap_miss counter over-credited page
cache hits during fault-arounds and page-fault retries. This results in
significant reduction of redundant synchronous mmap readahead I/O,
drastically cutting down execution time and gigabytes read for sparse
random or strided memory access workloads.
- The 2 patch series "selftests/cgroup: Fix false positive failures in
test_percpu_basic" from Li Wang fixes a couple of false-positives in the
cgroup kmem selftests.
- The 2 patch series "mm/damon/reclaim: support monitoring intervals
auto-tuning" from SeongJae Park adds a new parameter to DAMON permitting
DAMON_RECLAIM to automatically tune DAMON's sampling and aggregation
intervals.
- The 2 patch series "mm/damon/stat: add kdamond_pid parameter" from
SeongJae Park chnges DAMON_STAT to provide the pid of its kdamond.
- The 2 patch series "mm/kmemleak: dedupe verbose scan output" from
Breno Leitao removes large amounts of duplicated backtraces from the
verbose-mode kmemleak output.
- The 8 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)"
from David Hildenbrand reduces our use of CONFIG_HAVE_BOOTMEM_INFO_NODE,
with a view to removing it entirely in a later series.
- The 2 patch series "mm/damon: validate min_region_size to be power of
2" from Liew Rui Yan prevents users from passing a non-power-of-2 value
of `addr_unit', as this later results in undesirable behavior.
- The 2 patch series "mm: document read_pages and simplify usage" from
Frederick Mayle does as claimed.
- The 3 patch series "tools/mm/page-types: Fix misc bugs" from Ye Liu
fixes three issues in tools/mm/page-types.c.
- The 4 patch series "mm: misc cleanups from __GFP_UNMAPPED series" from
Brendan Jackman implements several cleanups in the page allocator and
related code.
- The 12 patch series "mm, swap: swap table phase IV: unify allocation"
from Kairui Song unifies the allocation and charging of anon and shmem
swap in folios, provides better synchronization, consolidates the
metadata management, hence dropping the static array and map, and
improves performance.
- The 28 patch series "mm/damon: introduce data attributes monitoring"
from SeongJae Park extends DAMON for monitoring general data attributes
other than accesses.
- The 5 patch series "mm/vmalloc: free unused pages on vrealloc()
shrink" from Shivam Kalra implements the TODO in vrealloc() to unmap and
free unused pages when shrinking across a page boundary.
- The 3 patch series "mm/damon: documentation and comment fixes" from
niecheng does as advertised.
- The 3 patch series "remove mmap_action success, error hooks" from
Lorenzo Stoakes eliminates custom hooks from mmap_action by removing the
problematic success_hook which allowed drivers to improperly access
uninitialized VMAs. It replaces the error_hook with a simple error-code
field and updates the memory char driver accordingly.
- The 14 patch series "mm/damon: minor improvements for code readability
and tests" from SeongJae Park implements minor improvements in code
readability and tests for DAMON.
- The 2 patch series "mm/damon: fix macro arguments and clarify quota
goals doc" from Maksym Shcherba does those things.
- The 2 patch series "userfaultfd: merge fs/userfaultfd.c into
mm/userfaultfd.c" from Mike Rapoport performs that code movement.
- The 15 patch series "mm/mglru: improve reclaim loop and dirty folio"
from Kairui Song and others cleans up and slightly improves MGLRU's
reclaim loop and dirty writeback handling. Large performance
improvements are measured.
- The 3 patch series "use vma locks for proc/pid/{smaps|numa_maps}
reads" from Suren Baghdasaryan uses per-vma locks when reading
/proc/pid/smaps and /proc/pid/numa_maps similar to reduce contention on
central mmap_lock.
- The 2 patch series "refactors thpsize_shmem_enabled_store() and
thpsize_shmem_enabled_show()" from Ran Xiaokai provides some cleanup
work in the THP code.
- The 2 patch series "selftests/memfd: fix compilation warnings" from
Konstantin Khorenko fixes a few build glitches in the memfd selftest
code.
- The 4 patch series "memcg: shrink obj_stock_pcp and cache multiple
objcgs" from Shakeel Butt resolves a 68% performance regression caused
by NUMA-node cache thrashing around struct obj_stock_pcp by shrinking
its existing fields and expanding it into a multi-slot array that caches
up to five obj_cgroup pointers per CPU, allowing per-node variants of
the same memcg to coexist within a single 64-byte cache line.
- The 2 patch series "zram: writeback fixes" from Sergey Senozhatsky
addresses a couple of unrelated zram writeback issues.
- The 9 patch series "mm: switch THP shrinker to list_lru" from Johannes
Weiner resolves NUMA-awareness issues and streamlines callsite
interaction by refactoring and extending the list_lru API to completely
replace the complex, open-coded deferred split queue for Transparent
Huge Pages (THPs).
- The 2 patch series "mm: improve large folio readahead for exec memory"
from Usama Arif improves large-folio readahead on systems like 64K-page
arm64 by preventing the mmap_miss check from permanently disabling
target-oriented VM_EXEC readahead, and by generalizing the
force_thp_readahead gate to support mappings with any usefully large
maximum folio order under the cache cap.
- The 6 patch series "userfaultfd/pagemap: pre-existing fixes" from
Kiryl Shutsemau fixes a bunch of minor issues in the
userfaultfd/pagemap, all of which were flagged by Sashiko review of
proposed new material.
- The 5 patch series "mm/sparse-vmemmap: Provide generic
vmemmap_set_pmd() and vmemmap_check_pmd()" from Muchun Song provides
generic versions of these two functions so the four arch-specific
implementations can be removed.
- The 2 patch series "mm/swap, PM: hibernate: fix swapoff race in
uswsusp by pinning swap device" from Youngjun Park addresses a
uswsusp-vs-swapoff race and reduces the swap device reference
taking/releasing frequency.
- The 2 patch series "mm/hmm: A fix and a selftest" from Dev Jain does
as claimed.
