614  res等于all under rcu_read_lock
615  如果此条件成立可能性小(为编译器优化)(res)则
616  如果res大于0则mnt = NULL
618  dentry = NULL
619  返回:false
621  如果此条件成立可能性小(为编译器优化)(! 有引用则递增计数)则
622  dentry = NULL
623  返回:false
625  返回:非ad_seqcount_retry - end a seq-read critical section*@s: pointer to seqcount_t*@start: count, from read_seqcount_begin* Returns: 1 if retry is required, else 0* read_seqcount_retry closes a read critical section of the given seqcount
