[PATCH v3] [mm-unstable] mm: Fix memcg reclaim on memory tiered systems (Mina Almasry) https://lkml.kernel.org/r/20221206023406.3182800-1-almasrymina@google.com
There was a patch for enabling demotion via memory.reclaim memcg file. It made try_to_free_mem_cgroup_pages() behavior changed. As the changed behavior is somewhat the users of the caller didn’t expect, this patch fixes it.
[PATCHv8 00/14] mm, x86/cc: Implement support for unaccepted memory (Kirill A. Shutemov) https://lkml.kernel.org/r/20221207014933.8435-1-kirill.shutemov@linux.intel.com
Some confidential VM approaches like Intel TDX or AMD SEV-SNP requires the guests to accept memory that they will use before use.

Lockdep and KMSAN are known to work together nowadays, though it could make kernel run slower. This patch fixes KMSAN’s false positives on wq_head->lock->dep_map.
[PATCH] mm/huge_memory: add TRANSPARENT_HUGEPAGE_NEVER for THP (ye xingchen) https://lkml.kernel.org/r/202211301651462590168@zte.com.cn
This patch adds a new kernel config called TRANSPARENT_HUGEPAGE_NEVER, which will set the value of /sys/kernel/mm/transparent_hugepage/enabled [never].

drop_caches works in somewhat loop-until-no-progress manner. It could result in not so aggressive reclamation. This patch makes it to continue reclamation on other node until every node makes no progress.
[RFC][PATCH 0/4] cachestat: a new syscall for page cache state of files (Nha Pham) https://lkml.kernel.org/r/20221115182901.2755368-1-nphamcs@gmail.com
Users can know the cache state of files using mincore() system call, but it scales bad for large files.

This patch makes page_reporting_param_ops static, as it’s used in only the c file.
[RFC PATCH] mm: introduce accounting of page_owner via backtrace (Zhoyang Huang) https://lkml.kernel.org/r/1667390781-17515-1-git-send-email-zhaoyang.huang@unisoc.com
This RFC patchset accounts and sorts page_owner output via its backtrace for simplifying it.
[PATCH v6 0/5] THP Shrinker (Alexander Zhu) https://lkml.kernel.org/r/cover.1667454613.git.alexlzhu@fb.com
The patchset for THP shrinking, which aims to reduce memory waste due to the THP underutilization, has revised again to the sixth version.
[PATCH] swap: add a limit for readahead page-cluster value (Kairu Song) https://lkml.kernel.org/r/20221023162533.81561-1-ryncsn@gmail.com
/proc/sys/vm/page-cluster could overflow because it has no upper limit. This patch set its upper-limit as 2**31, so that at most 2**31 pages could be read in at once.
