Message-Id: <742911348237311@web12h.yandex.ru> Date: Fri, 21 Sep 2012 18:21:51 +0400 From: Kirill Tkhai <tkhai@...dex.ru> To: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Cc: Steven Rostedt <rostedt@...dmis.org>, Ingo Molnar <mingo@...e.hu>, Peter Zijlstra <peterz@...radead.org> Subject: Re: [PATCH]sched/rt.c: leaf_rt_rq_list contains empty queues. Fix it Second version. Add every not empty queue once. The patch: Function __enqueue_rt_entity() adds an empty queue to leaf_rt_rq_list. So, pick_next_highest_task_rt() picks empty queues. Fix it.
