146  循环
147  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
148  fprop_reflect_period_single(p, pl)
149  num等于he local events counter
150  den等于percpu_counter is intended to track positive numbers. In the UP case the* number should never be negative.
151  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
157  如果den小于等于num则
158  如果num则den等于num
160  否则den等于1
163  denominator等于den
164  numerator等于num
