[PATCH 1/3] xfs: check that the mountpoint is actually mounted in _supports_xfs_scrub

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a sanity check that the passed in mount point is actually mounted
to guard against actually calling _supports_xfs_scrub before
$SCRATCH_MNT is mounted.
