Paul E. McKenney 39953dfd40 rcu: Avoid misordering in __call_rcu_nocb_enqueue() ... The NOCB leader wakeup ordering depends on the store to the header happening before the check for the leader already being awake. However, because atomic_long_add() does not return a value, it does not provide ordering guarantees, the incorrect comment in wake_nocb_leader() notwithstanding. This commit therefore adds a smp_mb__after_atomic() after the final atomic_long_add() to provide the needed ordering guarantee. Reported-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Paul E.
