Hello!

This series provides some nocb callback-offloading updates:

1.	rcu/nocb: Protect lazy shrinker against concurrent
	(de-)offloading, courtesy of Frederic Weisbecker.

2.	rcu/nocb: Fix shrinker race against callback enqueuer, courtesy
	of Frederic Weisbecker.

3.	rcu/nocb: Recheck lazy callbacks under the ->nocb_lock from
	shrinker, courtesy of Frederic Weisbecker.

4.	rcu/nocb: Make shrinker to iterate only NOCB CPUs, courtesy of
	Frederic Weisbecker.

						Thanx, Paul
