Thanks Eryu. I had started to write this test but ran into another bug
(where xfs blows past the maximum inode space %) so got distracted.
I see Dave's already picked apart the patch so I won't comment specifically
on it, but you might be aware of the possibility that xfs won't stop when
we hit the default imaxpct, and may actually fill the entire fs. That's
not necessarily a problem but it may take longer than you expect.
I also wonder what's necessary to actually test the sibling pointer problem;
on xfs, it's probably just a sufficiently large directory, not necessarily
a full fs?
