Paul E. McKenney 0a0ba1c93f rcu: Adjust ->lock acquisition for tasks no longer migrating ... Tasks are no longer migrated away from a given rcu_node structure when all CPUs corresponding to that rcu_node structure have gone offline. This means that rcu_read_unlock_special() no longer needs to loop retrying rcu_node ->lock acquisition because the current task is guaranteed to stay put. This commit takes a small and paranoid step towards relying on this guarantee by placing a WARN_ON_ONCE() just after the early exit from the lock-acquisition loop. Signed-off-by: Paul E.
