Type:void

Parameter:

TypeParameterName
struct fprop_global *p
struct fprop_local_single *pl
unsigned long *numerator
unsigned long *denominator
146  Do
147  seq = 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 = he local events counter
150  den = percpu_counter is intended to track positive numbers. In the UP case the* number should never be negative.
151  When 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 cycle
157  If den <= num Then
158  If num Then den = num
160  Else den = 1
163  denominator = den
164  numerator = num
