函数原型：static void __blk_mq_complete_request(struct request *rq)

返回类型：void

参数：

类型参数名称
struct request *rq
562  ctx等于mq_ctx
563  q等于q
564  bool shared = false
567  WRITE_ONCE(state, MQ_RQ_COMPLETE)
577  如果nr_hw_queues恒等于1则
578  __blk_complete_request(rq)
579  返回
586  如果 op and common flags 按位与REQ_HIPRI或非test_bit(complete on same CPU-group , & * various queue flags, see QUEUE_* below)则
588  complete(rq)
589  返回
592  cpu等于get_cpu()
593  如果非test_bit(rce complete on same CPU , & * various queue flags, see QUEUE_* below)则shared等于cpus_share_cache(cpu, cpu)
596  如果cpu不等于cpu且非shared且cpu_online(cpu)则
597  func等于__blk_mq_complete_request_remote
598  info等于rq
599  flags等于0
