Merge tag 'mm-stable-2022-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM updates from Andrew Morton:
 "Most of the MM queue. A few things are still pending.

  Liam's maple tree rework didn't make it. This has resulted in a few
  other minor patch series being held over for next time.

  Multi-gen LRU still isn't merged as we were waiting for mapletree to
  stabilize. The current plan is to merge MGLRU into -mm soon and to
  later reintroduce mapletree, with a view to hopefully getting both
  into 6.1-rc1.

  Summary:

   - The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe
     Lin, Yang Shi, Anshuman Khandual and Mike Rapoport

   - Some kmemleak fixes from Patrick Wang and Waiman Long

   - DAMON updates from SeongJae Park

   - memcg debug/visibility work from Roman Gushchin

   - vmalloc speedup from Uladzislau Rezki

   - more folio conversion work from Matthew Wilcox

   - enhancements for coherent device memory mapping from Alex Sierra

   - addition of shared pages tracking and CoW support for fsdax, from
     Shiyang Ruan

   - hugetlb optimizations from Mike Kravetz

   - Mel Gorman has contributed some pagealloc changes to improve
     latency and realtime behaviour.

   - mprotect soft-dirty checking has been improved by Peter Xu

   - Many other singleton patches all over the place"

+==========================
+DAMON:数据访问监视器
+==========================
+
+DAMON是Linux内核的一个数据访问监控框架子系统。DAMON的核心机制使其成为
+（该核心机制详见(Documentation/translations/zh_CN/mm/damon/design.rst)）
+
+ - *准确度* （监测输出对DRAM级别的内存管理足够有用；但可能不适合CPU Cache级别），
+ - *轻量级* （监控开销低到可以在线应用），以及
+ - *可扩展* （无论目标工作负载的大小，开销的上限值都在恒定范围内）。
+
+因此，利用这个框架，内核的内存管理机制可以做出高级决策。会导致高数据访问监控开销的实
+验性内存管理优化工作可以再次进行。同时，在用户空间，有一些特殊工作负载的用户可以编写
+个性化的应用程序，以便更好地了解和优化他们的工作负载和系统。
