The patch series which are included in this merge do the following: - Peng Zhang has done some mapletree maintainance work in the series "maple_tree: add mt_free_one() and mt_attr() helpers" "Some cleanups of maple tree" - In the series "mm: use memmap_on_memory semantics for dax/kmem" Vishal Verma has altered the interworking between memory-hotplug and dax/kmem so that newly added 'device memory' can more easily have its memmap placed within that newly added memory. - Matthew Wilcox continues folio-related work (including a few fixes) in the patch series "Add folio_zero_tail() and folio_fill_tail()" "Make folio_start_writeback return void" "Fix fault handler's handling of poisoned tail pages" "Convert aops->error_remove_page to ->error_remove_folio" "Finish two folio conversions" "More swap folio conversions" - Kefeng Wang has also contributed folio-related work in the series "mm: cleanup and use more folio in page fault" - Jim Cromie has improved the kmemleak reporting output in the series "tweak kmemleak report format". - In the series "stackdepot: allow evicting stack traces" Andrey Konovalov to permits clients (in this case KASAN) to cause eviction of no longer needed stack traces. - Charan Teja Kalla has fixed some accounting issues in the page allocator's atomic reserve calculations in the series "mm: page_alloc: fixes for high atomic reserve caluculations". - Dmitry Rokosov has added to the samples/ dorectory some sample code for a userspace memcg event listener application. See the series "samples: introduce cgroup events listeners". - Some mapletree maintanance work from Liam Howlett in the series "maple_tree: iterator state changes". - Nhat Pham has improved zswap's approach to writeback in the series "workload-specific and memory pressure-driven zswap writeback". - DAMON/DAMOS feature and maintenance work from SeongJae Park in the series "mm/damon: let users feed and tame/auto-tune DAMOS" "selftests/damon: add Python-written DAMON functionality tests" "mm/damon: misc updates for 6.8" - Yosry Ahmed has improved memcg's stats flushing in the series "mm: memcg: subtree stats flushing and thresholds". - In the series "Multi-size THP for anonymous memory" Ryan Roberts has added a runtime opt-in feature to transparent hugepages which improves performance by allocating larger chunks of memory during anonymous page faults. - Matthew Wilcox has also contributed some cleanup and maintenance work against eh buffer_head code int he series "More buffer_head cleanups". - Suren Baghdasaryan has done work on Andrea Arcangeli's series "userfaultfd move option". UFFDIO_MOVE permits userspace heap compaction algorithms to move userspace's pages around rather than UFFDIO_COPY'a alloc/copy/free. - Stefan Roesch has developed a "KSM Advisor", in the series "mm/ksm: Add ksm advisor". This is a governor which tunes KSM's scanning aggressiveness in response to userspace's current needs. - Chengming Zhou has optimized zswap's temporary working memory use in the series "mm/zswap: dstmem reuse optimizations and cleanups". - Matthew Wilcox has performed some maintenance work on the writeback code, both code and within filesystems. The series is "Clean up the writeback paths". - Andrey Konovalov has optimized KASAN's handling of alloc and free stack traces for secondary-level allocators, in the series "kasan: save mempool stack traces". - Andrey also performed some KASAN maintenance work in the series "kasan: assorted clean-ups". - David Hildenbrand has gone to town on the rmap code. Cleanups, more pte batching, folio conversions and more. See the series "mm/rmap: interface overhaul". - Kinsey Ho has contributed some maintenance work on the MGLRU code in the series "mm/mglru: Kconfig cleanup". - Matthew Wilcox has contributed lruvec page accounting code cleanups in the series "Remove some lruvec page accounting functions". ---------------------------------------------------------------- Alexander Gordeev (2): pgtable: fix s390
