Date: Sun, 18 Aug 2013 16:25:20 +0800 From: Lei Wen <leiwen@...vell.com> To: Paul Turner <pjt@...gle.com>, Peter Zijlstra <peterz@...radead.org>, Ingo Molnar <mingo@...e.hu>, <mingo@...hat.com>, <leiwen@...vell.com>, <linux-kernel@...r.kernel.org> Subject: [PATCH 6/8] sched: change find_busiest_queue to h_nr_running Since find_busiest_queue try to avoid do load balance for runqueue which has only one cfs task and its load is above the imbalance value calculated, we should use h_nr_running of cfs instead of nr_running of rq.
