From: Darrick J. Wong <djwong@xxxxxxxxxx>
If the kernel says it doesn't support optimizing a data structure, we
should mark it done and move on. This is much better than requeuing the
repair, in which case it will likely keep failing. Eventually these
requeued repairs end up in the single-threaded last resort at the end of
phase 4, which makes things /very/ slow.
