Plus of course many indivudual patches which are described in their changelogs. - "Allocate and free frozen pages" from Matthew Wilcox reorganizes the page allocator so we end up with the ability to allocate and free zero-refcount pages. So that callers (ie, slab) can avoid a refcount inc & dec. - "Support large folios for tmpfs" from Baolin Wang teaches tmpfs to use large folios other than PMD-sized ones. - "Fix mm/rodata_test" from Petr Tesarik performs some maintenance and fixes for this small built-in kernel selftest. - "mas_anode_descend() related cleanup" from Wei Yang tidies up part of the mapletree code. - "mm: fix format issues and param types" from Keren Sun implements a few minor code cleanups. - "simplify split calculation" from Wei Yang provides a few fixes and a test for the mapletree code. - "mm/vma: make more mmap logic userland testable" from Lorenzo Stoakes continues the work of moving vma-related code into the (relatively) new mm/vma.c. - "mm/page_alloc: gfp flags cleanups for alloc_contig_*()" from David Hildenbrand cleans up and rationalizes handling of gfp flags in the page allocator. - "readahead: Reintroduce fix for improper RA window sizing" from Jan Kara is a second attempt at fixing a readahead window sizing issue. It should reduce the amount of unnecessary reading. - "synchronously scan and reclaim empty user PTE pages" from Qi Zheng addresses an issue where "huge" amounts of pte pagetables are accumulated (https://lore.kernel.org/lkml/cover.1718267194.git.zhengqi.arch@bytedance.com/). Qi's series addresses this windup by synchronously freeing PTE memory within the context of madvise(MADV_DONTNEED). - "selftest/mm: Remove warnings found by adding compiler flags" from Muhammad Usama Anjum fixes some build warnings in the selftests code when optional compiler warnings are enabled. - "mm: don't use __GFP_HARDWALL when migrating remote pages" from David Hildenbrand tightens the allocator's observance of __GFP_HARDWALL. - "pkeys kselftests improvements" from Kevin Brodsky implements various fixes and cleanups in the MM selftests code, mainly pertaining to the pkeys tests. - "mm/damon: add sample modules" from SeongJae Park enhances DAMON to estimate application working set size. - "memcg/hugetlb: Rework memcg hugetlb charging" from Joshua Hahn provides some cleanups to memcg's hugetlb charging logic. - "mm/swap_cgroup: remove global swap cgroup lock" from Kairui Song removes the global swap cgroup lock. A speedup of 10% for a tmpfs-based kernel build was demonstrated. - "zram: split page type read/write handling" from Sergey Senozhatsky has several fixes and cleaups for zram in the area of zram_write_page(). A watchdog softlockup warning was eliminated. - "move pagetable_*_dtor() to __tlb_remove_table()" from Kevin Brodsky cleans up the pagetable destructor implementations. A rare use-after-free race is fixed. - "mm/debug: introduce and use VM_WARN_ON_VMG()" from Lorenzo Stoakes simplifies and cleans up the debugging code in the VMA merging logic. - "Account page tables at all levels" from Kevin Brodsky cleans up and regularizes the pagetable ctor/dtor handling. This results in improvements in accounting accuracy. - "mm/damon: replace most damon_callback usages in sysfs with new core functions" from SeongJae Park cleans up and generalizes DAMON's sysfs file interface logic. - "mm/damon: enable page level properties based monitoring" from SeongJae Park increases the amount of information which is presented in response to DAMOS actions. - "mm/damon: remove DAMON debugfs interface" from SeongJae Park removes DAMON's long-deprecated debugfs interfaces. Thus the migration to sysfs is completed. - "mm/hugetlb: Refactor hugetlb allocation resv accounting" from Peter Xu cleans up and generalizes the hugetlb reservation accounting. - "mm: alloc_pages_bulk: small API refactor" from Luiz Capitulino removes a never-used feature of the alloc_pages_bulk() interface. - "mm/damon: extend DAMOS filters for inclusion" from SeongJae Park extends DAMOS filters to support not only exclusion (rejecting), but also inclusion (allowing) behavior. - "Add zpdesc memory descriptor for zswap.zpool" from Alex Shi "introduces a new memory descriptor for zswap.zpool that currently overlaps with struct page for now. This is part of the effort to reduce the size of struct page and to enable dynamic allocation of memory descriptors." - "mm, swap: rework of swap allocator locks" from Kairui Song redoes and simplifies the swap allocator locking. A speedup of 400% was demonstrated for one workload. As was a 35% reduction for kernel build time with swap-on-zram. - "mm: update mips to use do_mmap(), make mmap_region() internal" from Lorenzo Stoakes reworks MIPS's use of mmap_region() so that mmap_region() can be made MM-internal. - "mm/mglru: performance optimizations" from Yu Zhao fixes a few MGLRU regressions and otherwise improves MGLRU performance. - "Docs/mm/damon: add tuning guide and misc updates" from SeongJae Park updates DAMON documentation. - "Cleanup for memfd_create()" from Isaac Manjarres does that thing. - "mm: hugetlb+THP folio and migration cleanups" from David Hildenbrand provides various cleanups in the areas of hugetlb folios, THP folios and migration. - "Uncached buffered IO" from Jens Axboe implements the new RWF_DONTCACHE flag which provides synchronous dropbehind for pagecache reading and writing. To permite userspace to address issues with massive buildup of useless pagecache when reading/writing fast devices. - "selftests/mm: virtual_address_range: Reduce memory" from Thomas Weißschuh fixes and optimizes some of the MM selftests. ---------------------------------------------------------------- Alex Shi (7): mm/zsmalloc: add zpdesc memory descriptor for zswap.zpool mm/zsmalloc: use zpdesc in trylock_zspage()/lock_zspage() mm/zsmalloc: convert create_page_chain() and its users to use zpdesc mm/zsmalloc: convert reset_page to reset_zpdesc mm/zsmalloc: convert SetZsPageMovable and remove unused funcs mm/zsmalloc: convert get/set_first_obj_offset() to take zpdesc mm/zsmalloc: introduce __zpdesc_clear/set_zsmalloc() Alexander Gordeev (1): s390/mm: add missing ctor/dtor on page table upgrade Alice Ryhl (2): mm/zswap: add LRU_STOP to comment about dropping the lru lock list_lru: expand list_lru_add() docs with info about sublists Andrew Morton (3): mm/damon/tests/vaddr-kunit.h: reduce stack consumption mm/huge_memory.c: rename shadowed local Documentation/filesystems/proc.rst: fix possessive form of "process" Baolin Wang (6): mm: factor out the order calculation into a new helper mm: shmem: change shmem_huge_global_enabled() to return huge order bitmap mm: shmem: add large folio support for tmpfs mm: shmem: add a kernel command line to change the default huge policy for tmpfs docs: tmpfs: drop 'fadvise()' from the documentation mm: shmem: skip swapcache for swapin of synchronous swap device Bruno Faccini (1): mm/fake-numa: allow later numa node hotplug Byungchul Park (1): mm: separate move/undo parts from migrate_pages_batch() Chen Ridong (1): memcg: fix soft lockup in the OOM process Chin Yik Ming (1): mm/memory: fix a comment typo in lock_mm_and_find_vma() Christoph Hellwig (1): mm: unexport apply_to_existing_page_range David Hildenbrand (17): docs: tmpfs: update the large folios policy for tmpfs and shmem mm/memory_hotplug: move debug_pagealloc_map_pages() into online_pages_range() mm/page_isolation: don't pass gfp flags to isolate_single_pageblock() mm/page_isolation: don't pass gfp flags to start_isolate_page_range() mm/page_alloc: make __alloc_contig_migrate_range() static mm/page_alloc: sort out the alloc_contig_range() gfp flags mess mm/page_alloc: forward the gfp flags from alloc_contig_range() to post_alloc_hook() powernv/memtrace: use __GFP_ZERO with alloc_contig_pages() mm/hugetlb: don't map folios writable without VM_WRITE when copying during fork() mm/page_alloc: don't use __GFP_HARDWALL when migrating pages via alloc_contig*() mm/memory_hotplug: don't use __GFP_HARDWALL when migrating pages via memory offlining mm/huge_memory: convert has_hwpoisoned into a pure folio flag mm/hugetlb: rename isolate_hugetlb() to folio_isolate_hugetlb() mm/migrate: don't call folio_putback_active_hugetlb() on dst hugetlb folio mm/hugetlb: rename folio_putback_active_hugetlb() to folio_putback_hugetlb() mm/hugetlb-cgroup: convert hugetlb_cgroup_css_offline() to work on folios mm/hugetlb: use folio->lru int demote_free_hugetlb_folios() Donet Tom (2): mm: migrate: remove unused argument vma from migrate_misplaced_folio() selftests/mm: add new test cases to the migration test Dr. David Alan Gilbert (1): filemap: remove unused folio_add_wait_queue Gregory Price (1): mm: add build-time option for hotplug memory default online type Guillaume Morin (1): mm/hugetlb: support FOLL_FORCE|FOLL_WRITE Guo Weikang (4): mm/shmem: refactor to reuse vfs_parse_monolithic_sep for option parsing mm/early_ioremap: add null pointer checks to prevent NULL-pointer dereference mm/memmap: prevent double scanning of memmap by kmemleak mm/memblock: add memblock_alloc_or_panic interface Hao Ge (1): selftests/mm/cow: modify the incorrect checking parameters Honggyu Kim (1): mm/damon/core: remove duplicate list_empty quota->goals check Hyeonggon Yoo (12): mm/migrate: remove slab checks in isolate_movable_page() mm/zsmalloc: convert __zs_map_object/__zs_unmap_object to use zpdesc mm/zsmalloc: add and use pfn/zpdesc seeking funcs mm/zsmalloc: convert obj_malloc() to use zpdesc mm/zsmalloc: convert obj_allocated() and related helpers to use zpdesc mm/zsmalloc: convert init_zspage() to use zpdesc mm/zsmalloc: convert obj_to_page() and zs_free() to use zpdesc mm/zsmalloc: add two helpers for zs_page_migrate() and make it use zpdesc mm/zsmalloc: convert __free_zspage() to use zpdesc mm/zsmalloc: convert location_to_obj() to take zpdesc mm/zsmalloc: convert migrate_zspage() to use zpdesc mm/zsmalloc: convert get_zspage() to take zpdesc Isaac J.
