6ebf98d71f9b509e833e0af00795ad3723d2f410 - mm: introduce CONFIG_NUMA_MIGRATION and simplify CONFIG_MIGRATION

Thu, 19 Mar 2026 09:19:41 +0100

mm: introduce CONFIG_NUMA_MIGRATION and simplify CONFIG_MIGRATIONCONFIG_MEMORY_HOTREMOVE, CONFIG_COMPACTION and CONFIG_CMA all selectCONFIG_MIGRATION, because they require it to work (users).Only CONFIG_NUMA_BALANCING and CONFIG_BALLOON_MIGRATION depend onCONFIG_MIGRATION. CONFIG_BALLOON_MIGRATION is not an actual user, but animplementation of migration support, so the dependency is correct(CONFIG_BALLOON_MIGRATION does not make any sense withoutCONFIG_MIGRATION).However, kconfig-language.rst clearly states "In general use select onlyfor non-visible symbols". So far CONFIG_MIGRATION is user-visible ... and the dependencies rather confusing.The whole reason why CONFIG_MIGRATION is user-visible is because ofCONFIG_NUMA: some users might want CONFIG_NUMA but not page migrationsupport.Let's clean all that up by introducing a dedicated CONFIG_NUMA_MIGRATIONconfig option for that purpose only. Make CONFIG_NUMA_BALANCING that sofar depended on CONFIG_NUMA && CONFIG_MIGRATION to depend onCONFIG_MIGRATION instead. CONFIG_NUMA_MIGRATION will depend onCONFIG_NUMA && CONFIG_MMU.CONFIG_NUMA_MIGRATION is user-visible and will default to "y". We usethat default so new configs will automatically enable it, just like it wasthe case with CONFIG_MIGRATION. The downside is that some configs thatused to have CONFIG_MIGRATION=n might get it re-enabled byCONFIG_NUMA_MIGRATION=y, which shouldn't be a problem.CONFIG_MIGRATION is now a non-visible config option. Any code that selectCONFIG_MIGRATION (as before) must depend directly or indirectly onCONFIG_MMU.CONFIG_NUMA_MIGRATION is responsible for any NUMA migration code, which ismempolicy migration code, memory-tiering code, and move_pages() code inmigrate.c. CONFIG_NUMA_BALANCING uses its functionality.Note that this implies that with CONFIG_NUMA_MIGRATION=n, move_pages()will not be available even though CONFIG_MIGRATION=y, which is an expectedchange.In migrate.c, we can remove the CONFIG_NUMA check as bothCONFIG_NUMA_MIGRATION and CONFIG_NUMA_BALANCING depend on it.With this change, CONFIG_MIGRATION is an internal config, all users ofmigration selects CONFIG_MIGRATION, and only CONFIG_BALLOON_MIGRATIONdepends on it.Link: https://lkml.kernel.org/r/20260319-config_migration-v1-2-42270124966f@kernel.orgSigned-off-by: David Hildenbrand (Arm) Reviewed-by: Lorenzo Stoakes (Oracle) Acked-by: Zi Yan Reviewed-by: Jonathan Cameron Cc: Albert Ou Cc: Alexander Gordeev Cc: Alexandre Ghiti Cc: Alistair Popple Cc: "Borislav Petkov (AMD)" Cc: Byungchul Park Cc: Catalin Marinas Cc: Christian Borntraeger Cc: Gregory Price Cc: Heiko Carstens Cc: "H.

mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVEPatch series "mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE and cleanupCONFIG_MIGRATION".While working on memory hotplug code cleanups, I realized thatCONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE is not really required anymore.Changing that revealed some rather nasty looking CONFIG_MIGRATIONhandling.Let's clean that up by introducing a dedicated CONFIG_NUMA_MIGRATIONoption and reducing the dependencies that CONFIG_MIGRATION has.This patch (of 2):All architectures that select CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE alsoselect CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG. So we can just removeCONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE.For CONFIG_MIGRATION, make it depend on CONFIG_MEMORY_HOTREMOVE instead,and make CONFIG_MEMORY_HOTREMOVE select CONFIG_MIGRATION (just likeCONFIG_CMA and CONFIG_COMPACTION already do).We'll clean up CONFIG_MIGRATION next.Link: https://lkml.kernel.org/r/20260319-config_migration-v1-0-42270124966f@kernel.orgLink: https://lkml.kernel.org/r/20260319-config_migration-v1-1-42270124966f@kernel.orgSigned-off-by: David Hildenbrand (Arm) Acked-by: Zi Yan Reviewed-by: Lorenzo Stoakes (Oracle) Reviewed-by: Joshua Hahn Reviewed-by: Gregory Price Reviewed-by: Mike Rapoport (Microsoft) Reviewed-by: Jonathan Cameron Cc: Albert Ou Cc: Alexander Gordeev Cc: Alexandre Ghiti Cc: Alistair Popple Cc: "Borislav Petkov (AMD)" Cc: Byungchul Park Cc: Catalin Marinas Cc: Christian Borntraeger Cc: Heiko Carstens Cc: "H.

slab,rcu: disable KVFREE_RCU_BATCHED for strict grace periodDisable CONFIG_KVFREE_RCU_BATCHED in CONFIG_RCU_STRICT_GRACE_PERIOD buildsso that kernel fuzzers have an easier time finding use-after-free involvingkfree_rcu().The intent behind CONFIG_RCU_STRICT_GRACE_PERIOD is that RCU should invokecallbacks and free objects as soon as possible (at a large performancecost) so that kernel fuzzers and such have an easier time detectinguse-after-free bugs in objects with RCU lifetime.CONFIG_KVFREE_RCU_BATCHED is a performance optimization that queuesRCU-freed objects in ways that CONFIG_RCU_STRICT_GRACE_PERIOD can'texpedite; for example, the following testcase doesn't trigger a KASAN splatwhen CONFIG_KVFREE_RCU_BATCHED is enabled:```struct foo_struct { struct rcu_head rcu; int a;};struct foo_struct *foo = kmalloc(sizeof(*foo), GFP_KERNEL | __GFP_NOFAIL | __GFP_ZERO);pr_info("%s: calling kfree_rcu()\n", __func__);kfree_rcu(foo, rcu);msleep(10);pr_info("%s: start UAF access\n", __func__);READ_ONCE(foo->a);pr_info("%s: end UAF access\n", __func__);```Signed-off-by: Jann Horn Acked-by: David Rientjes Reviewed-by: Joel Fernandes Acked-by: Harry Yoo (Oracle) Link: https://patch.msgid.link/20260324-kasan-kfree-rcu-v1-1-ac58a7a13d03@google.comSigned-off-by: Vlastimil Babka (SUSE) List of files: /linux/mm/Kconfig

Large improvements during demand faulting are demonstrated (David Hildenbrand) - "memcg cleanups" tidies up some memcg code (Chen Ridong) - "mm/damon: introduce {,max_}nr_snapshots and tracepoint for damos stats" improves DAMOS stat's provided information, deterministic control, and readability (SeongJae Park) - "selftests/mm: hugetlb cgroup charging: robustness fixes" fixes a few issues in the hugetlb cgroup charging selftests (Li Wang) - "Fix va_high_addr_switch.sh test failure - again" addresses several issues in the va_high_addr_switch test (Chunyu Hu) - "mm/damon/tests/core-kunit: extend existing test scenarios" improves the KUnit test coverage for DAMON (Shu Anzai) - "mm/khugepaged: fix dirty page handling for MADV_COLLAPSE" fixes a glitch in khugepaged which was causing madvise(MADV_COLLAPSE) to transiently return -EAGAIN (Shivank Garg) - "arch, mm: consolidate hugetlb early reservation" reworks and consolidates a pile of straggly code related to reservation of hugetlb memory from bootmem and creation of CMA areas for hugetlb (Mike Rapoport) - "mm: clean up anon_vma implementation" cleans up the anon_vma implementation in various ways (Lorenzo Stoakes) - "tweaks for __alloc_pages_slowpath()" does a little streamlining of the page allocator's slowpath code (Vlastimil Babka) - "memcg: separate private and public ID namespaces" cleans up the memcg ID code and prevents the internal-only private IDs from being exposed to userspace (Shakeel Butt) - "mm: hugetlb: allocate frozen gigantic folio" cleans up the allocation of frozen folios and avoids some atomic refcount operations (Kefeng Wang) - "mm/damon: advance DAMOS-based LRU sorting" improves DAMOS's movement of memory betewwn the active and inactive LRUs and adds auto-tuning of the ratio-based quotas and of monitoring intervals (SeongJae Park) - "Support page table check on PowerPC" makes CONFIG_PAGE_TABLE_CHECK_ENFORCED work on powerpc (Andrew Donnellan) - "nodemask: align nodes_and{,not} with underlying bitmap ops" makes nodes_and() and nodes_andnot() propagate the return values from the underlying bit operations, enabling some cleanup in calling code (Yury Norov) - "mm/damon: hide kdamond and kdamond_lock from API callers" cleans up some DAMON internal interfaces (SeongJae Park) - "mm/khugepaged: cleanups and scan limit fix" does some cleanup work in khupaged and fixes a scan limit accounting issue (Shivank Garg) - "mm: balloon infrastructure cleanups" goes to town on the balloon infrastructure and its page migration function. Mainly cleanups, also some locking simplification (David Hildenbrand) - "mm/vmscan: add tracepoint and reason for kswapd_failures reset" adds additional tracepoints to the page reclaim code (Jiayuan Chen) - "Replace wq users and add WQ_PERCPU to alloc_workqueue() users" is part of Marco's kernel-wide migration from the legacy workqueue APIs over to the preferred unbound workqueues (Marco Crivellari) - "Various mm kselftests improvements/fixes" provides various unrelated improvements/fixes for the mm kselftests (Kevin Brodsky) - "mm: accelerate gigantic folio allocation" greatly speeds up gigantic folio allocation, mainly by avoiding unnecessary work in pfn_range_valid_contig() (Kefeng Wang) - "selftests/damon: improve leak detection and wss estimation reliability" improves the reliability of two of the DAMON selftests (SeongJae Park) - "mm/damon: cleanup kdamond, damon_call(), damos filter and DAMON_MIN_REGION" does some cleanup work in the core DAMON code (SeongJae Park) - "Docs/mm/damon: update intro, modules, maintainer profile, and misc" performs maintenance work on the DAMON documentation (SeongJae Park) - "mm: add and use vma_assert_stabilised() helper" refactors and cleans up the core VMA code. The main aim here is to be able to use the mmap write lock's lockdep state to perform various assertions regarding the locking which the VMA code requires (Lorenzo Stoakes) - "mm, swap: swap table phase II: unify swapin use" removes some old swap code (swap cache bypassing and swap synchronization) which wasn't working very well. Various other cleanups and simplifications were made. The end result is a 20% speedup in one benchmark (Kairui Song) - "enable PT_RECLAIM on more 64-bit architectures" makes PT_RECLAIM available on 64-bit alpha, loongarch, mips, parisc, and um. Various cleanups were performed along the way (Qi Zheng)* tag 'mm-stable-2026-02-11-19-22' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (325 commits) mm/memory: handle non-split locks correctly in zap_empty_pte_table() mm: move pte table reclaim code to memory.c mm: make PT_RECLAIM depends on MMU_GATHER_RCU_TABLE_FREE mm: convert __HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE config um: mm: enable MMU_GATHER_RCU_TABLE_FREE parisc: mm: enable MMU_GATHER_RCU_TABLE_FREE mips: mm: enable MMU_GATHER_RCU_TABLE_FREE LoongArch: mm: enable MMU_GATHER_RCU_TABLE_FREE alpha: mm: enable MMU_GATHER_RCU_TABLE_FREE mm: change mm/pt_reclaim.c to use asm/tlb.h instead of asm-generic/tlb.h mm/damon/stat: remove __read_mostly from memory_idle_ms_percentiles zsmalloc: make common caches global mm: add SPDX id lines to some mm source files mm/zswap: use %pe to print error pointers mm/vmscan: use %pe to print error pointers mm/readahead: fix typo in comment mm: khugepaged: fix NR_FILE_PAGES and NR_SHMEM in collapse_file() mm: refactor vma_map_pages to use vm_insert_pages mm/damon: unify address range representation with damon_addr_range mm/cma: replace snprintf with strscpy in cma_new_area ...
