Christ. Now really attached.

I'll just go back to bed, because today is just not working out. Maybe
things will be better tomorrow.

Or maybe I should start drinking, and at least have an excuse.

Thanks for reverting the broken commit.  I'll work on a proper fix for
the readdir() issue for the next merge cycle, and make sure it gets
proper testing.

I'll also take care of packaging up Greg's test program and getting it
submitted to xfstests so we have a proper regression test case.
