McKenney <paulmck@xxxxxxxxxxxxx> CommitDate: Tue, 27 Nov 2018 09:18:59 -0800 crypto/pcrypt: Replace synchronize_rcu_bh() with synchronize_rcu() Now that synchronize_rcu() waits for bh-disable regions of code as well as RCU read-side critical sections, the synchronize_rcu_bh() in pcrypt_cpumask_change_notify() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E.
