From 900404e5d201d0a6d2806f615b41e939713d55db Mon Sep 17 00:00:00 2001 From: Charles Wang Date: Mon, 20 Aug 2012 16:02:33 +0800 Subject: [PATCH] sched: Add missing call to calc_load_exit_idle() commit 749c8814f08f12baa4a9c2812a7c6ede7d69507d upstream. Azat Khuzhin reported high loadavg in Linux v3.6 After checking the upstream scheduler code, I found Peter's commit: 5167e8d5417b sched/nohz: Rewrite and fix load-avg computation -- again not fully applied, missing the call to calc_load_exit_idle(). After that idle exit in sampling window will always be calculated to non-idle, and the load will be higher than normal. This patch adds the missing call to calc_load_exit_idle().
