Johannes Weiner has arranged for zswap memory use to be tracked and managed on a per-cgroup basis. Munchun Song adds a /proc knob ("hugetlb_optimize_vmemmap") for runtime enablement of the recent huge page vmemmap optimization feature. Baolin Wang contributes a series to fix some issues around hugetlb pagetable invalidation. Zhenwei Pi has fixed some interactions between hwpoisoned pages and virtualization. Tong Tiangen has enabled the use of the presently x86-only page_table_check debugging feature on arm64 and riscv. David Vernet has done some fixup work on the memcg selftests. Peter Xu has taught userfaultfd to handle write protection faults against shmem- and hugetlbfs-backed files. More DAMON development from SeongJae Park - adding online tuning of the feature and support for monitoring of fixed virtual address ranges. Also easier discovery of which monitoring operations are available. Nadav Amit has done some optimization of TLB flushing during mprotect(). Neil Brown continues to labor away at improving our swap-over-NFS support. David Hildenbrand has some fixes to anon page COWing versus get_user_pages(). Peng Liu fixed some errors in the core hugetlb code. Joao Martins has reduced the amount of memory consumed by device-dax's compound devmaps. Some cleanups of the arch-specific pagemap code from Anshuman Khandual. Muchun Song has found and fixed some errors in the TLB flushing of transparent hugepages. Roman Gushchin has done more work on the memcg selftests. And, of course, many smaller fixes and cleanups. Notably, the customary million cleanup serieses from Miaohe Lin. ---------------------------------------------------------------- Adrian Huang (1): mm/rmap: Fix typos in comments Akira Yokosawa (1): docs: vm/page_owner: tweak literal block in STANDARD FORMAT SPECIFIERS Alexey Romanov (1): zram: remove double compression logic Alistair Popple (1): mm: add selftests for migration entries Andrey Konovalov (7): kasan: mark KASAN_VMALLOC flags as kasan_vmalloc_flags_t kasan: clean up comments in internal kasan.h kasan: use tabs to align shadow values kasan: give better names to shadow values kasan: update documentation kasan: move boot parameters section in documentation kasan: clean-up kconfig options descriptions Anshuman Khandual (8): mm/debug_vm_pgtable: drop protection_map[] usage mm/mmap: clarify protection_map[] indices mm/mmap: add new config ARCH_HAS_VM_GET_PAGE_PROT powerpc/mm: enable ARCH_HAS_VM_GET_PAGE_PROT arm64/mm: enable ARCH_HAS_VM_GET_PAGE_PROT sparc/mm: enable ARCH_HAS_VM_GET_PAGE_PROT mm/mmap: drop arch_filter_pgprot() mm/mmap: drop arch_vm_get_page_pgprot() Axel Rasmussen (2): selftests: vm: refactor run_vmtests.sh to reduce boilerplate selftests: vm: fix shellcheck warnings in run_vmtests.sh Baolin Wang (8): mm: migrate: simplify the refcount validation when migrating hugetlb mapping mm: hugetlb: add missing cache flushing in hugetlb_unshare_all_pmds() mm: hugetlb: considering PMD sharing when flushing cache/TLBs mm: rmap: move the cache flushing to the correct place for hugetlb PMD sharing mm: rmap: use flush_cache_range() to flush cache for hugetlb pages mm: change huge_ptep_clear_flush() to return the original pte mm: rmap: fix CONT-PTE/PMD size hugetlb issue when migration mm: rmap: fix CONT-PTE/PMD size hugetlb issue when unmapping Brian Geffon (1): zram: add a huge_idle writeback mode Chen Wandun (2): mm: rework calculation of bdi_min_ratio in bdi_set_min_ratio mm/page_alloc: simplify update of pgdat in wake_all_kswapds Christoph Hellwig (1): x86/mm: enable ARCH_HAS_VM_GET_PAGE_PROT Christophe JAILLET (2): drivers/base/memory: fix an unlikely reference counting issue in __add_memory_block() cgroup: fix an error handling path in alloc_pagecache_max_30M() Christophe de Dinechin (1): nodemask.h: fix compilation error with GCC12 David Hildenbrand (25): mm/rmap: fix missing swap_free() in try_to_unmap() after arch_unmap_one() failed mm/hugetlb: take src_mm->write_protect_seq in copy_hugetlb_page_range() mm/memory: slightly simplify copy_present_pte() mm/rmap: split page_dup_rmap() into page_dup_file_rmap() and page_try_dup_anon_rmap() mm/rmap: convert RMAP flags to a proper distinct rmap_t type mm/rmap: remove do_page_add_anon_rmap() mm/rmap: pass rmap flags to hugepage_add_anon_rmap() mm/rmap: drop "compound" parameter from page_add_new_anon_rmap() mm/rmap: use page_move_anon_rmap() when reusing a mapped PageAnon() page exclusively mm/huge_memory: remove outdated VM_WARN_ON_ONCE_PAGE from unmap_page() mm/page-flags: reuse PG_mappedtodisk as PG_anon_exclusive for PageAnon() pages mm: remember exclusively mapped anonymous pages with PG_anon_exclusive mm/rmap: fail try_to_migrate() early when setting a PMD migration entry fails mm/gup: disallow follow_page(FOLL_PIN) mm: support GUP-triggered unsharing of anonymous pages mm/gup: trigger FAULT_FLAG_UNSHARE when R/O-pinning a possibly shared anonymous page mm/gup: sanity-check with CONFIG_DEBUG_VM that anonymous pages are exclusive when (un)pinning mm/swap: remember PG_anon_exclusive via a swp pte bit mm/debug_vm_pgtable: add tests for __HAVE_ARCH_PTE_SWP_EXCLUSIVE x86/pgtable: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE arm64/pgtable: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE s390/pgtable: cleanup description of swp pte layout s390/pgtable: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE powerpc/pgtable: remove _PAGE_BIT_SWAP_TYPE for book3s powerpc/pgtable: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE for book3s David Vernet (5): cgroups: refactor children cgroups in memcg tests cgroup: account for memory_recursiveprot in test_memcg_low() cgroup: account for memory_localevents in test_memcg_oom_group_leaf_events() cgroup: remove racy check in test_memcg_sock() cgroup: fix racy check in alloc_pagecache_max_30M() helper function Eric Dumazet (1): mm/page_owner: use strscpy() instead of strlcpy() Fabio M.
