[PATCH 0/2] resurrect

[Pavel Begunkov <asml.silence@gmail.com>]

Combined approach with tryget, fallbacking to trying completion and
doing synchronize_rcu, where the last one is very unlikely to happen
and limited by one such per register syscall.

I expect 1/2 to cleanly apply for stable, 2/2 needs to be backported
by hand.
