For one, I didn't get around to look at his series yet, so I simply
can't know that this series addresses the same issue. I'm fine
dropping the patch here, but as said in reply to a similar comment
by him the patch here (as well as the PV counterpart) has the
advantage of being a backporting candidate; the other series
pretty clearly isn't, afaict.
