Subject: [PATCH 6/7] sched/deadline: depend on clearing throttled status in replenish_dl_entity
Date: Mon, 6 Apr 2015 16:53:18 +0800 [thread overview]
Message-ID: <1428310399-13489-6-git-send-email-wanpeng.li@linux.intel.com> (raw)
In-Reply-To: <1428310399-13489-1-git-send-email-wanpeng.li@linux.intel.com>
Since the natural place to clear ->dl_throttled is in replenish_dl_entity(), and
the task which is adjusted the priority is the current, it will be dequeued and
then enqueued w/ replenish which can guarantee ->dl_throttled can be cleared,
this patch drop the clear throttled status in function rt_mutex_setprio.
