Date: Mon, 1 Jul 2013 20:33:22 +0800 From: Lei Wen <leiwen@...vell.com> To: Paul Turner <pjt@...gle.com>, Alex Shi <alex.shi@...el.com>, Peter Zijlstra <peterz@...radead.org>, Ingo Molnar <mingo@...e.hu>, <mingo@...hat.com>, Kamalesh Babulal <kamalesh@...ux.vnet.ibm.com>, Lei Wen <leiwen@...vell.com>, <linux-kernel@...r.kernel.org> Subject: [V2 2/2] sched: update cfs_rq weight earlier in enqueue_entity Since we are going to calculate cfs_rq's average ratio by runnable_load_avg/load.weight, if not increase the load.weight prior to enqueue_entity_load_avg, it may lead to one cfs_rq's avg ratio higher than 100%. Adjust the sequence, so that all ratio is kept below 100%.
