That's not what I'm saying at all. I wrote these patches 3 months ago,
and like I mentioned, I think doing the futex2 flags for that side is a
good suggestion from Peter. As those initial prep patches are all these
require, rather than the full futex2 series, there's no reason not to
review these at the same time too, if people should be so inclined.

We're now resorting to name calling? Sorry, but I think that's pretty
low and not very professional.

I'm not asking anyone to rush anything.

Again, you're making assumptions.

It's Peter's series, I'm not going to split his series and step on his
toes. I already separately tested, and will do so with the updated
series as well when I get back, since I saw he posted one.
