From 67aa0f767af488a7f1e41cccb4f7a4893f24a1ab Mon Sep 17 00:00:00 2001 From: Luis Henriques Date: Tue, 24 Mar 2009 22:10:02 +0000 Subject: sched: remove unused fields from struct rq Impact: cleanup, new schedstat ABI Since they are used on in statistics and are always set to zero, the following fields from struct rq have been removed: yld_exp_empty, yld_act_empty and yld_both_empty. Both Sched Debug and SCHEDSTAT_VERSION versions has also been incremented since ABIs have been changed. The schedtop tool has been updated to properly handle new version of schedstat: http://rt.wiki.kernel.org/index.php/Schedtop_utility Signed-off-by: Luis Henriques Acked-by: Gregory Haskins Acked-by: Peter Zijlstra LKML-Reference: <20090324221002.GA10061@hades.domain.com> Signed-off-by: Ingo Molnar --- kernel/sched_stats.h | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'kernel/sched_stats.h') diff --git a/kernel/sched_stats.h b/kernel/sched_stats.h index a8f93dd374e..32d2bd4061b 100644 --- a/kernel/sched_stats.h +++ b/kernel/sched_stats.h @@ -4,7 +4,7 @@ * bump this up when changing the output format or the meaning of an existing * format, so that tools can adapt (or abort) */ -#define SCHEDSTAT_VERSION 14 +#define SCHEDSTAT_VERSION 15 static int show_schedstat(struct seq_file *seq, void *v) { @@ -26,9 +26,8 @@ static int show_schedstat(struct seq_file *seq, void *v) /* runqueue-specific stats */ seq_printf(seq, - "cpu%d %u %u %u %u %u %u %u %u %u %llu %llu %lu", - cpu, rq->yld_both_empty, - rq->yld_act_empty, rq->yld_exp_empty, rq->yld_count, + "cpu%d %u %u %u %u %u %u %llu %llu %lu", + cpu, rq->yld_count, rq->sched_switch, rq->sched_count, rq->sched_goidle, rq->ttwu_count, rq->ttwu_local, rq->rq_cpu_time, -- cgit v1.2.3
