   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.
