I don't think you need $SCRATCH_DEV and _require_scratch in this helper,
a test file just does the work, e.g. creating an empty file somewhere
and using the "-d name=<filename>,size=<size>" option of mkfs.xfs to do
the test.

"newer mkfs" is not specific, it's not clear which version of xfsprogs
one should use to run this test. It'd be good to see specific version
info in this message if possible. (Sorry I didn't make my point clear in
previous reviews.)
