   > @anchao Did you confirm that this PR works in SMP mode without any side effects?
   
   sched_lock/sched_unlock can't protect the resource in SMP mode. All code which depend on sched_lock/sched_unlock to protect the resource must be change to the critical section, spinlock or semaphore as soon as we can.
