函数名称：ktime_get_raw - Returns the raw monotonic time in ktime_t format

函数原型：ktime_t ktime_get_raw(void)

返回类型：ktime_t

参数：无

856  tk等于timekeeper
861  循环
862  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
863  base等于base
864  nsecs等于timekeeping_get_ns( & tkr_raw)
866  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
868  返回:Add a ktime_t variable and a scalar nanosecond value.* res = kt + nsval:(base, nsecs)
