Merge tag 'for-6.1-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs fixes from David Sterba:
 "A batch of error handling fixes for resource leaks, fixes for nowait
  mode in combination with direct and buffered IO:

   - direct IO + dsync + nowait could miss a sync of the file after
     write, add handling for this combination

   - buffered IO + nowait should not fail with ENOSPC, only blocking IO
     could determine that

   - error handling fixes:
      - fix inode reserve space leak due to nowait buffered write
      - check the correct variable after allocation (direct IO submit)
      - fix inode list leak during backref walking
      - fix ulist freeing in self tests"
