From 2ddbf952508fb9911036c484a87f6351106b917c Mon Sep 17 00:00:00 2001 From: Hiroshi Shimamoto Date: Mon, 15 Oct 2007 17:00:11 +0200 Subject: [PATCH] sched: clean up sched_fork() The adjusting sched_class is a missing part of the already existing "do not leak PI boosting priority to the child" at the sched_fork(). This patch moves the adjusting sched_class from wake_up_new_task() to sched_fork(). this also shrinks the code a bit: text data bss dec hex filename 40111 4018 292 44421 ad85 sched.o.before 40102 4018 292 44412 ad7c sched.o.after Signed-off-by: Hiroshi Shimamoto Signed-off-by: Dmitry Adamushko Signed-off-by: Ingo Molnar Reviewed-by: Thomas Gleixner --- kernel/sched.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/kernel/sched.c b/kernel/sched.c index 36484da963..cd2b4942fe 100644 --- a/kernel/sched.c +++ b/kernel/sched.c @@ -1663,6 +1663,8 @@ void sched_fork(struct task_struct *p, int clone_flags) * Make sure we do not leak PI boosting priority to the child: */ p->prio = current->normal_prio; + if (!rt_prio(p->prio)) + p->sched_class = &fair_sched_class; #if defined(CONFIG_SCHEDSTATS) || defined(CONFIG_TASK_DELAY_ACCT) if (likely(sched_info_on())) @@ -1698,11 +1700,6 @@ void fastcall wake_up_new_task(struct task_struct *p, unsigned long clone_flags) p->prio = effective_prio(p); - if (rt_prio(p->prio)) - p->sched_class = &rt_sched_class; - else - p->sched_class = &fair_sched_class; - if (task_cpu(p) != this_cpu || !p->sched_class->task_new || !current->se.on_rq) { activate_task(rq, p, 0); -- 2.39.5
