1. Memory management

• memory control group

  • Extend the shrink file to shrink all memcg caches for the slab cache. Before the commit, writing 1 to /sys/kernel/slab/<slab>/shrink was shrinking only the root cache. With SLUB_MEMCG_SYSFS_ON enabled and slub_memcg_sysfs=1 used, it was possible to shrink also memcg caches, but it was impractical. Now all memcg caches will be shrunk when writing to the "global" shrink file. commit

  • Throttle allocators when reclaim cannot keep up with v2 memory.high limit commit

  • Introduce gradual reclaim pressure between v2 memory.low and memory.min thresholds instead of the previous cliff behavior. commit commit commit

  • Improve situation with multiple parallel reclaimers by letting each walk through the whole cgroup tree, resulting in fewer premature OOM kills. commit

  • Deprecate v1 kmem.limit_in_bytes due to causing unexpected ENOMEM failures and global OOM's. commit

  • Prevent premature OOM's due to deferred THP split queue. commit commit commit commit

• Introduce madvise() flags MADV_COLD, which marks pages as inactive (thus more easily reclaimed under memory pressure), but doesn't discard the contents like MADV_FREE does, and MADV_PAGEOUT, which reclaims pages immediately, but doesn't discard the contents like MADV_DONTNEED does. commit commit commit commit

• Experientally enable THP support for text section (executable code) of non-shmem files (CONFIG_READ_ONLY_THP_FOR_FS) commit commit commit commit commit commit commit

• Change the handling of THP page faults so that they are tried first on a local NUMA node with no memory reclaim allowed, and if they not succeed, for madvise(MADV_HUGEPAGE) areas retry on all nodes, allowing reclaim. This should prevent swap storms observed on pre-5.3 kernels with some workloads and also fix the reported regression for a different workload on 5.3 kernel. LWN merge commit commit commit commit commit

• Make uprobes uprobe THP-aware. Instead of splitting whole THP when installing uprobe, split only the huge PMD, and reinstate it after uprobes are removed. commit commit commit commit commit commit

• kmemleak: make it more robust during early allocations (before slab subsystem is initialized) by using a single memory pool commit commit commit commit commit commit

• KASAN: for software tag-based mode, enhance the memory corruption report with a guess whether it is "use-after-free" or "out-of-bound" error instead of "invalid-access" error. commit

• Introduce page_shift(), page_size() and compound_nr() to make common operations with compound pages simpler and more readable. commit commit commit

• page_owner: store also the stack of who last freed the page and print it in dump_page() to improve debugging double free or use-after-free, especially when debug_pagealloc or KASAN are also enabled commit commit commit commit commit commit

• oom: add task UID, oom_score_adj and pgtables to OOM message commit commit

• Fix minuters or hours long stalls when setting nr_hugepages to too high values. commit commit commit commit

• Provide a generic top-down mmap layout implementation and use it for riscv. commit commit commit commit commit commit commit commit commit commit commit commit commit commit

• zswap: let zswap use movable memory with zsmalloc commit commit

• Guarantee alignment to size for kmalloc() allocations of power-of-two size, regardless of used sla*b allocator and activated debugging functions. LWN commit commit

* X86

• Add UMIP emulation/spoofing for 64-bit processes as well, because of Wine based gaming commit
