unsigned long *	numerator
unsigned long *	denominator

Do

235

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

236

fprop_reflect_period_percpu(p, pl)

237

num = percpu_counter is intended to track positive numbers. In the UP case the* number should never be negative.

238

den = percpu_counter is intended to track positive numbers. In the UP case the* number should never be negative.

239

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

245

If den <= num Then

246

If num Then den = num

248

Else den = 1

251

denominator = den

252

numerator = num

__fprop_inc_percpu_max	Like __fprop_inc_percpu() except that event is counted only if the given* type has fraction smaller than @max_frac/FPROP_FRAC_BASE
