file-backed transparent hugepages. 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. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCYo52xQAKCRDdBJ7gKXxA jtJFAQD238KoeI9z5SkPMaeBRYSRQmNll85mxs25KapcEgWgGQD9FAb7DJkqsIVk PzE+d9hEfirUGdL6cujatwJ6ejYR8Q8= =nFe6 -----END PGP SIGNATURE----- Merge tag 'mm-stable-2022-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: "Almost all of MM here.
