From: Darrick J. Wong <djwong@xxxxxxxxxx>
In commit 725feeff, I forgot that xfs has *not* always supported all
swap file configurations -- the bmap swapfile activation prior to the
introduction of iomap_swapfile_activate did not permit the use of
unwritten extents in the swap file. Therefore, kick xfs out of the
always-supported list.
Fixes: 725feeff ("common/rc: swapon should not fail for given FS in _require_scratch_swapfile()")
