Ross - when you get a failure in a brand new test in xfstests
(xfs/118 was merged about a month ago), it's worth checking whether
the problem is already fixed in the XFS for-next tree. In general,
the regression tests exercising such bugs aren't merged until the
fix has been committed...

Yes. The above commit is marked for stable, so it will be appearing
in all those older kernels in the next few weeks...

Cheers,
