类型参数名称
struct timespec64 *ts
2162  tk等于timekeeper
2165  循环
2166  seq等于ad_seqcount_begin - begin a seq-read critical section*@s: pointer to seqcount_t* Returns: count to be passed to read_seqcount_retry* read_seqcount_begin opens a read critical section of the given seqcount
2168  ts等于tk_xtime(tk)
2169 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循环
