Thanks for the updated patch! Some minor comments inline.

Could you please add jfs support to _scratch_mkfs_sized in a separate
patch?

This is not needed, SCRATCH_DEV will be unmounted by next test that
calls _require_scratch.

Because this test is trying to consume all space on $SCRATCH_MNT, it'd
be good to exit if _scratch_mount fails, otherwise it's filling rootfs.
_scratch_mount || _fail "mount failed"

Hmm, fstests prefer:
TFILE=$SCRATCH_MNT/testfile.$seq
touch $TFILE
chmod u_rwx $TFILE
...
instead of cd to $SCRATCH_MNT.

$SCRATCH_DEV was just created, no need to remove $TFILE here.

How about just writing 50M to $TFILE?

Should be in auto and quick group too. Basically auto group means this
test is a well defined regression test and the run time is less than
300s, quick group is a subset of auto, and the run time is usually
within 30s.
