$metadump_file is not used in this test.

Seems above line is copied & pasted from _check_xfs_filesystem(), but
there's no $extra_log_options defined in this test.

You can use get_block_size() helper, and I know I've mentioned it before :)

Better to have some comments on the numbers and why require such a fs
space, as you did in your last reply.

_check_generic_filesystem runs "fsck -t $FSTYP $dev" but "fsck -t xfs"
is a no-op, and $metadump_file is a metadump, not a fs image. Perhaps
what you want to do is "_check_scratch_fs $TEST_DIR/image"?

$SCRATCH_MNT should not be mounted at this point, so there's no point
checksuming $SCRATCH_MNT/f1 here.
