From c71758c426fd1c0e04b6f870b57c0434cb73246a Mon Sep 17 00:00:00 2001
From: Vincent Guittot <vincent.guittot@linaro.org>
Date: Tue, 8 Nov 2016 10:53:47 +0100
Subject: [PATCH 12/92] sched/fair: Fix task group initialization
The moves of tasks are now propagated down to root and the utilization
of cfs_rq reflects reality so it doesn't need to be estimated at init.
