I was going to go over the series today with 4.14 in mind. Looks to me like this should really be 2-3 patch series, that depend on each other. Might be better for review purposes as well. So I'd agree with Bart - can we get this split a bit and geared towards what we need for 4.14 at least, since it's getting close. And some of the changes do make me somewhat nervous, they need proper cooking time. -- Jens Axboe
