stop_machine: Provide RCU quiescent state in multi_cpu_stop() When multi_cpu_stop() loops waiting for other tasks, it can trigger an RCU CPU stall warning. This can be misleading because what is instead needed is information on whatever task is blocking multi_cpu_stop(). This commit therefore inserts an RCU quiescent state into the multi_cpu_stop() function's waitloop. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
