init_task's preempt_notifiers is initialized at two times.
1) sched_init() -> INIT_HLIST_HEAD(&init_task.preempt_notifiers) 2) sched_init() -> init_idle(current,) <--- current task is init_task at this time -> __sched_fork(,current) -> INIT_HLIST_HEAD(&p->preempt_notifiers)
I think first one is needless, remove it.
