This commit therefore corrects checklist.txt to encourage use of the underlying rcu_barrier() API. Signed-off-by: Joel Fernandes (Google) Signed-off-by: Paul E.

You instead need to use one of the barrier functions: o call_rcu() -> rcu_barrier() - o call_rcu_bh() -> rcu_barrier_bh() - o call_rcu_sched() -> rcu_barrier_sched() + o call_rcu_bh() -> rcu_barrier() + o call_rcu_sched() -> rcu_barrier() o call_srcu() -> srcu_barrier() However, these barrier functions are absolutely -not- guaranteed
