参数：

类型参数名称
struct timespec64 *ts
2175  tk等于timekeeper
2179  循环
2180  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
2182  now等于tk_xtime(tk)
2183  mono等于wall_to_monotonic
2184  当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
2186  set_normalized_timespec - set timespec sec and nsec parts and normalize*@ts: pointer to timespec variable to be set*@sec: seconds to set*@nsec: nanoseconds to set* Set seconds and nanoseconds field of a timespec variable and* normalize to the timespec
