From 810b38179e9e4d4f57b4b733767bb08f8291a965 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 29 Feb 2008 15:21:01 -0500 Subject: sched: retain vruntime Kei Tokunaga reported an interactivity problem when moving tasks between control groups. Tasks would retain their old vruntime when moved between groups, this can cause funny lags. Re-set the vruntime on group move to fit within the new tree.
