Everything looks fine. But I am already sleeping now ;)

Rafael, Tejun, I'll try to re-read 1-4 tomorrow. I do not expect I'll
find something interesting, just I am paranoid.

Looks like, 1/4 could have an additional note in the changelog, with
this patch we avoid the unnecessary try_to_freeze_cgroup() and this
looks like a win to me...

Oleg.
