Sorry for this typo, I'll fix it.

Hmm...  why rmapbt=1 cause logbsize=16k can't be displayed in /proc/mounts?

Actually set MKFS_OPTIONS="" is not helpful for this case, due to I run
"$MKFS_XFS_PROG -f $* $LOOP_DEV" directly. I strip out MKFS_OPTIONS,
because I use SCRACH_DEV at first :)

Maybe we should avoid the testing about those behaviors can't be sure, if we
can't make it have a fixed output.
