Subject: [PATCH v3 6/6] sched/rt: Use resched_curr() in task_tick_rt()
Date: Mon, 22 Sep 2014 22:36:43 +0400 [thread overview]
Message-ID: <20140922183642.11015.66039.stgit@localhost> (raw)
In-Reply-To: <20140922183612.11015.64200.stgit@localhost>
From: Kirill Tkhai <ktkhai@parallels.com>
Some time ago PREEMPT_NEED_RESCHED was implemented,
so reschedule technics is a little more difficult now.
