When configure SCRATCH_DEV to a mount point (and not to a directory therein) then user will get a false positive error in scratch tests: $SCRATCH_DEV=/mnt/base/scratch is mounted but not on $SCRATCH_MNT=/mnt/scratch Already mounted result: /dev/sda6 on /mnt/base/scratch type xfs (rw,relatime,attr2,inode64,noquota) This is due to the wrong `grep -F $SCRATCH_DEV` which matches the mount point instead of the device in that mount. Fix _check_mounted_on() to grep the pattern "$dev on " and "$dev on $mnt" instead of just grepping for "$dev" and "$mnt" without the " on " anchor.
