 - The 2 patch series "mm/vmscan: fix demotion targets checks in
   reclaim/demotion" from Bing Jiao fixes a couple of issues in the
   demotion code - pages were failed demotion and were finding themselves
   demoted into disallowed nodes.
 
 - The 11 patch series "Remove XA_ZERO from error recovery of dup_mmap()"
   from Liam Howlett fixes a rare mapledtree race and performs a number of
   cleanups.
 
 - The 13 patch series "mm: add bitmap VMA flag helpers and convert all
   mmap_prepare to use them" from Lorenzo Stoakes implements a lot of
   cleanups following on from the conversion of the VMA flags into a
   bitmap.
 
 - The 5 patch series "support batch checking of references and unmapping
   for large folios" from Baolin Wang implements batching to greatly
   improve the performance of reclaiming clean file-backed large folios.
 
 - The 3 patch series "selftests/mm: add memory failure selftests" from
   Miaohe Lin does as claimed.
