Merge tag 'fs-dedupe-last-block-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull fs deduplication fix from David Sterba:
 "This is a fix for deduplication bug: the last block of two files is
  allowed to deduplicated. This got broken in 5.1 by lifting some
  generic checks to VFS layer. The affected filesystems are btrfs and
  xfs.

  The patches are marked for stable as the bug decreases deduplication
  effectivity"

* tag 'fs-dedupe-last-block-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  Btrfs: make deduplication with range including the last block work
  fs: allow deduplication of eof block into the end of the destination file
