Peng Wang 423d02e146 sched/fair: Optimize dequeue_task_fair() ... While looking at enqueue_task_fair and dequeue_task_fair, it occurred to me that dequeue_task_fair can also be optimized as Vincent described in commit 7d148be69e ("sched/fair: Optimize enqueue_task_fair()"). When encountering throttled cfs_rq, dequeue_throttle label can ensure se not to be NULL, and rq->nr_running remains unchanged, so we can also skip the early balance check.
