From cd126afe838d7ea9b971cdea087fd498a7293c7f Mon Sep 17 00:00:00 2001 From: Yuyang Du Date: Wed, 15 Jul 2015 08:04:36 +0800 Subject: sched/fair: Remove rq's runnable avg The current rq->avg is not used at all since its merge into the kernel, and the code is in the scheduler's hot path, so remove it.
