mm/page_alloc: remove unnecessary __maybe_unused in order_to_pindex() (2025-03-21 22:03:17 -0700)
----------------------------------------------------------------
- The 6 patch series "Enable strict percpu address space checks" from
Uros Bizjak uses x86 named address space qualifiers to provide
compile-time checking of percpu area accesses.
This has caused a small amount of fallout - two or three issues were
reported. In all cases the calling code was founf to be incorrect.
- The 4 patch series "Some cleanup for memcg" from Chen Ridong
implements some relatively monir cleanups for the memcontrol code.
- The 17 patch series "mm: fixes for device-exclusive entries (hmm)"
from David Hildenbrand fixes a boatload of issues which David found then
using device-exclusive PTE entries when THP is enabled. More work is
needed, but this makes thins better - our own HMM selftests now succeed.
- The 2 patch series "mm: zswap: remove z3fold and zbud" from Yosry
Ahmed remove the z3fold and zbud implementations. They have been
deprecated for half a year and nobody has complained.
- The 5 patch series "mm: further simplify VMA merge operation" from
Lorenzo Stoakes implements numerous simplifications in this area. No
runtime effects are anticipated.
- The 4 patch series "mm/madvise: remove redundant mmap_lock operations
from process_madvise()" from SeongJae Park rationalizes the locking in
the madvise() implementation. Performance gains of 20-25% were observed
in one MADV_DONTNEED microbenchmark.
- The 12 patch series "Tiny cleanup and improvements about SWAP code"
from Baoquan He contains a number of touchups to issues which Baoquan
noticed when working on the swap code.
- The 2 patch series "mm: kmemleak: Usability improvements" from Catalin
Marinas implements a couple of improvements to the kmemleak user-visible
output.
- The 2 patch series "mm/damon/paddr: fix large folios access and
schemes handling" from Usama Arif provides a couple of fixes for DAMON's
handling of large folios.
- The 3 patch series "mm/damon/core: fix wrong and/or useless
damos_walk() behaviors" from SeongJae Park fixes a few issues with the
accuracy of kdamond's walking of DAMON regions.
- The 3 patch series "expose mapping wrprotect, fix fb_defio use" from
Lorenzo Stoakes changes the interaction between framebuffer deferred-io
and core MM. No functional changes are anticipated - this is
preparatory work for the future removal of page structure fields.
- The 4 patch series "mm/damon: add support for hugepage_size DAMOS
filter" from Usama Arif adds a DAMOS filter which permits the filtering
by huge page sizes.
- The 4 patch series "mm: permit guard regions for file-backed/shmem
mappings" from Lorenzo Stoakes extends the guard region feature from its
present "anon mappings only" state. The feature now covers shmem and
file-backed mappings.
- The 4 patch series "mm: batched unmap lazyfree large folios during
reclamation" from Barry Song cleans up and speeds up the unmapping for
pte-mapped large folios.
- The 18 patch series "reimplement per-vma lock as a refcount" from
Suren Baghdasaryan puts the vm_lock back into the vma. Our reasons for
pulling it out were largely bogus and that change made the code more
messy. This patchset provides small (0-10%) improvements on one
microbenchmark.
- The 5 patch series "Docs/mm/damon: misc DAMOS filters documentation
fixes and improves" from SeongJae Park does some maintenance work on the
DAMON docs.
- The 27 patch series "hugetlb/CMA improvements for large systems" from
Frank van der Linden addresses a pile of issues which have been observed
when using CMA on large machines.
- The 2 patch series "mm/damon: introduce DAMOS filter type for unmapped
pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the
page's mapped/unmapped status.
- The 19 patch series "zsmalloc/zram: there be preemption" from Sergey
Senozhatsky teaches zram to run its compression and decompression
operations preemptibly.
- The 12 patch series "selftests/mm: Some cleanups from trying to run
them" from Brendan Jackman fixes a pile of unrelated issues which
Brendan encountered while runnimg our selftests.
- The 2 patch series "fs/proc/task_mmu: add guard region bit to pagemap"
from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to
determine whether a particular page is a guard page.
- The 7 patch series "mm, swap: remove swap slot cache" from Kairui Song
removes the swap slot cache from the allocation path - it simply wasn't
being effective.
- The 5 patch series "mm: cleanups for device-exclusive entries (hmm)"
from David Hildenbrand implements a number of unrelated cleanups in this
code.
- The 5 patch series "mm: Rework generic PTDUMP configs" from Anshuman
Khandual implements a number of preparatoty cleanups to the
GENERIC_PTDUMP Kconfig logic.
- The 8 patch series "mm/damon: auto-tune aggregation interval" from
SeongJae Park implements a feedback-driven automatic tuning feature for
DAMON's aggregation interval tuning.
- The 5 patch series "Fix lazy mmu mode" from Ryan Roberts fixes some
issues in powerpc, sparc and x86 lazy MMU implementations. Ryan did
this in preparation for implementing lazy mmu mode for arm64 to optimize
vmalloc.
- The 2 patch series "mm/page_alloc: Some clarifications for migratetype
fallback" from Brendan Jackman reworks some commentary to make the code
easier to follow.
- The 3 patch series "page_counter cleanup and size reduction" from
Shakeel Butt cleans up the page_counter code and fixes a size increase
which we accidentally added late last year.
- The 3 patch series "Add a command line option that enables control of
how many threads should be used to allocate huge pages" from Thomas
Prescher does that. It allows the careful operator to significantly
reduce boot time by tuning the parallalization of huge page
initialization.
- The 3 patch series "Fix calculations in trace_balance_dirty_pages()
for cgwb" from Tang Yizhou fixes the tracing output from the dirty page
balancing code.
- The 9 patch series "mm/damon: make allow filters after reject filters
useful and intuitive" from SeongJae Park improves the handling of allow
and reject filters. Behaviour is made more consistent and the
documention is updated accordingly.
- The 5 patch series "Switch zswap to object read/write APIs" from Yosry
Ahmed updates zswap to the new object read/write APIs and thus permits
the removal of some legacy code from zpool and zsmalloc.
- The 6 patch series "Some trivial cleanups for shmem" from Baolin Wang
does as it claims.
- The 20 patch series "fs/dax: Fix ZONE_DEVICE page reference counts"
from Alistair Popple regularizes the weird ZONE_DEVICE page refcount
handling in DAX, permittig the removal of a number of special-case
checks.
- The 4 patch series "refactor mremap and fix bug" from Lorenzo Stoakes
is a preparatoty refactoring and cleanup of the mremap() code.
- The 20 patch series "mm: MM owner tracking for large folios (!hugetlb)
+ CONFIG_NO_PAGE_MAPCOUNT" from David Hildenbrand reworks the manner in
which we determine whether a large folio is known to be mapped
exclusively into a single MM.
- The 8 patch series "mm/damon: add sysfs dirs for managing DAMOS
filters based on handling layers" from SeongJae Park adds a couple of
new sysfs directories to ease the management of DAMON/DAMOS filters.
- The 13 patch series "arch, mm: reduce code duplication in mem_init()"
from Mike Rapoport consolidates many per-arch implementations of
mem_init() into code generic code, where that is practical.
- The 13 patch series "mm/damon/sysfs: commit parameters online via
damon_call()" from SeongJae Park continues the cleaning up of sysfs
access to DAMON internal data.
- The 3 patch series "mm: page_ext: Introduce new iteration API" from
Luiz Capitulino reworks the page_ext initialization to fix a boot-time
crash which was observed with an unusual combination of compile and
cmdline options.
- The 8 patch series "Buddy allocator like (or non-uniform) folio split"
from Zi Yan reworks the code to split a folio into smaller folios. The
main benefit is lessened memory consumption: fewer post-split folios are
generated.
- The 2 patch series "Minimize xa_node allocation during xarry split"
from Zi Yan reduces the number of xarray xa_nodes which are generated
during an xarray split.
- The 2 patch series "drivers/base/memory: Two cleanups" from Gavin Shan
performs some maintenance work on the drivers/base/memory code.
- The 3 patch series "Add tracepoints for lowmem reserves, watermarks
and totalreserve_pages" from Martin Liu adds some more tracepoints to
the page allocator code.
- The 4 patch series "mm/madvise: cleanup requests validations and
classifications" from SeongJae Park cleans up some warts which SeongJae
observed during his earlier madvise work.
- The 3 patch series "mm/hwpoison: Fix regressions in memory failure
handling" from Shuai Xue addresses two quite serious regressions which
Shuai has observed in the memory-failure implementation.
- The 5 patch series "mm: reliable huge page allocator" from Johannes
Weiner makes huge page allocations cheaper and more reliable by reducing
fragmentation.
- The 5 patch series "Minor memcg cleanups & prep for memdescs" from
Matthew Wilcox is preparatory work for the future implementation of
memdescs.
- The 4 patch series "track memory used by balloon drivers" from Nico
Pache introduces a way to track memory used by our various balloon
drivers.
- The 2 patch series "mm/damon: introduce DAMOS filter type for active
pages" from Nhat Pham permits users to filter for active/inactive pages,
separately for file and anon pages.
- The 2 patch series "Adding Proactive Memory Reclaim Statistics" from
Hao Jia separates the proactive reclaim statistics from the direct
reclaim statistics.
- The 2 patch series "mm/vmscan: don't try to reclaim hwpoison folio"
from Jinjiang Tu fixes our handling of hwpoisoned pages within the
reclaim code.
