Hi,
Just a couple of boring fixes related to the shrinker.
1/4: is related to (de-)offloading so the issue only concerns rcutorture right now (which doesn't seem to test lazy so hardly possible to trigger).
2/4: fix ignored flush, making the shrinker more efficient but nothing critical.
3/4: optimization
4/4: optimization
As such none of these patches carry a "Fixes:" because none fix an actual regression. Nothing worth backportng.
Frederic Weisbecker (4): rcu/nocb: Protect lazy shrinker against concurrent (de-)offloading rcu/nocb: Fix shrinker race against callback enqueuer rcu/nocb: Recheck lazy callbacks under the ->nocb_lock from shrinker rcu/nocb: Make shrinker to iterate only NOCB CPUs
