Pull erofs fixes from Gao Xiang:
 "The first one fixes a syzbot UAF report caused by a commit introduced
  in this cycle, but it also addresses a longstanding memory leak. The
  second one resolves a PSI memstall mis-accounting issue.

  The remaining patches switch file-backed mounts to use buffered I/Os
  by default instead of direct I/Os, since the page cache of underlay
  files is typically valid and maybe even dirty. This change also aligns
  with the default policy of loopback devices. A mount option has been
  added to try to use direct I/Os explicitly.

  Summary:

   - Fix (pcluster) memory leak and (sbi) UAF after umounting

   - Fix a case of PSI memstall mis-accounting

   - Use buffered I/Os by default for file-backed mounts"
