Seems fine to me, but for some reason you didn't CC all the people on
the series. Hence I don't know if each can stand on its own. A quick
grep tells me that, no, that is not the case, as
hrtimer_sleeper_task_get() isn't a thing in the tree right now.

That's a slight nudge to please don't do partial CCs, it's impossible to
tell without needing to dig further.
