From c66eaf619c0c7937e9ded160ae83b5a7a6b19b56 Mon Sep 17 00:00:00 2001 From: Paul Turner <pjt@google.com> Date: Mon, 15 Nov 2010 15:47:07 -0800 Subject: sched: Update shares on idle_balance Since shares updates are no longer expensive and effectively local, update them at idle_balance(). This allows us to more quickly redistribute shares to another cpu when our load becomes idle.
