bool gen_estimator_active	(	const struct gnet_stats_basic_packed *	bstats,
		const struct gnet_stats_rate_est *	rate_est
	)

gen_estimator_active - test if estimator is currently in use : basic statistics : rate estimator statistics

Returns true if estimator is active, and false if not.

Definition at line 308 of file gen_estimator.c.

void gen_kill_estimator	(	struct gnet_stats_basic_packed *	bstats,
		struct gnet_stats_rate_est *	rate_est
	)

gen_kill_estimator - remove a rate estimator : basic statistics : rate estimator statistics

Removes the rate estimator specified by &bstats and &rate_est.

Note : Caller should respect an RCU grace period before freeing stats_lock

Definition at line 260 of file gen_estimator.c.

int gen_new_estimator	(	struct gnet_stats_basic_packed *	bstats,
		struct gnet_stats_rate_est *	rate_est,
		spinlock_t *	stats_lock,
		struct nlattr *	opt
	)

gen_new_estimator - create a new rate estimator : basic statistics : rate estimator statistics : statistics lock : rate estimator configuration TLV

Creates a new rate estimator with &bstats as source and &rate_est as destination. A new timer with the interval specified in the configuration TLV is created. Upon each interval, the latest statistics will be read from &bstats and the estimated rate will be stored in &rate_est with the statistics lock grabed during this period.

Returns 0 on success or a negative error code.

Definition at line 205 of file gen_estimator.c.

int gen_replace_estimator	(	struct gnet_stats_basic_packed *	bstats,
		struct gnet_stats_rate_est *	rate_est,
		spinlock_t *	stats_lock,
		struct nlattr *	opt
	)

gen_replace_estimator - replace rate estimator configuration : basic statistics : rate estimator statistics : statistics lock : rate estimator configuration TLV

Replaces the configuration of a rate estimator by calling gen_kill_estimator() and gen_new_estimator().

Returns 0 on success or a negative error code.
