rcu/nocb: Make shrinker iterate only over NOCB CPUs Callbacks can only be queued as lazy on NOCB CPUs, therefore iterating over the NOCB mask is enough for both counting and scanning. Just lock the mostly uncontended barrier mutex on counting as well in order to keep rcu_nocb_mask stable. Signed-off-by: Frederic Weisbecker <frederic@kernel.org> Signed-off-by: Paul E.
