Thanks for considering my comment :) I looked through the series and
didn't see anything objectionable, but I'm not too in tune with the
various tests.

One thing that I was going to fix, but it would cause you merge
conflicts, is that right now dmesg-fail is considered to be "better"
than fail (when computing fixes/regressions). Similarly for dmesg-warn
vs warn. Mind flipping them? Should be a separate patch at the end of
the series. Or I can do it when you push.

Thanks,
