From: "Darrick J. Wong" <djwong@xxxxxxxxxx>
commit d4f74e162d238ce00a640af5f0611c3f51dad70e upstream.
The final parameter of filemap_write_and_wait_range is the end of the
range to flush, not the length of the range to flush.
Fixes: 46afb0628b86 ("xfs: only flush the unshared range in xfs_reflink_unshare")
