That's not a failure; it's just a skipped test.  (The check script
reports "Not run" separately from "Failures".)

xfs_scrub is something which is still in development.  It's in
Darrick's development tree in his xfsprogs-dev git tree on kernel.org,
but it's not in an officially supported release of xfsprogs yet, as
near as I can tell.

So it's not a big deal; you can just ignore the fact that it was
skipped.
