From 74b7eb5885415ed41d012f432398d1b697115b5f Mon Sep 17 00:00:00 2001 From: Yong Zhang Date: Fri, 29 Jan 2010 14:57:52 +0800 Subject: [PATCH] sched: Change usage of rt_rq->rt_se to rt_rq->tg->rt_se[cpu] This is the first step to remove rt_rq member rt_se because it have the same meaning with tg->rt_se[cpu]. And the latter style is also used by the fair scheduling class.
