How I understood Darrick's comment was that he was surprised by XFS numbers
we measured and he'd be interested if we see them also with the latest
kernel.  Nothing against the patch as such. And I wrote him that I can
queue XFS runs on current kernel (which didn't happen - my bad). I guess
time for me to really queue a test with the latest kernel.
