Subject: [PATCH] sched/core: remove check of p->sched_class
Date: Mon, 29 Dec 2014 14:41:43 +0800 [thread overview]
Message-ID: <1419835303-28958-1-git-send-email-yaodongdong@huawei.com> (raw)
Search all usage of p->sched_class in sched/core.c, no one check it
before use, so it seems that every task must belong to one sched_class.
