From 2de0b4639f4b1b6bfe31f795e5855f041f177170 Mon Sep 17 00:00:00 2001 From: Gregory Haskins Date: Fri, 25 Jan 2008 21:08:10 +0100 Subject: [PATCH] sched: RT balancing: include current CPU It doesn't hurt if we allow the current CPU to be included in the search. We will just simply skip it later if the current CPU turns out to be the lowest. We will use this later in the series Signed-off-by: Gregory Haskins Signed-off-by: Steven Rostedt Signed-off-by: Ingo Molnar --- kernel/sched_rt.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/kernel/sched_rt.c b/kernel/sched_rt.c index ffd02720b58f..95f36f61ae1d 100644 --- a/kernel/sched_rt.c +++ b/kernel/sched_rt.c @@ -277,9 +277,6 @@ static int find_lowest_rq(struct task_struct *task) for_each_cpu_mask(cpu, *cpu_mask) { struct rq *rq = cpu_rq(cpu); - if (cpu == rq->cpu) - continue; - /* We look for lowest RT prio or non-rt CPU */ if (rq->rt.highest_prio >= MAX_RT_PRIO) { lowest_rq = rq; @@ -307,7 +304,7 @@ static struct rq *find_lock_lowest_rq(struct task_struct *task, for (tries = 0; tries < RT_MAX_TRIES; tries++) { cpu = find_lowest_rq(task); - if (cpu == -1) + if ((cpu == -1) || (cpu == rq->cpu)) break; lowest_rq = cpu_rq(cpu); -- 2.20.1
