From 9b5b77512dce239fa168183fa71896712232e95a Mon Sep 17 00:00:00 2001 From: Srivatsa Vaddagiri Date: Mon, 15 Oct 2007 17:00:09 +0200 Subject: sched: clean up code under CONFIG_FAIR_GROUP_SCHED With the view of supporting user-id based fair scheduling (and not just container-based fair scheduling), this patch renames several functions and makes them independent of whether they are being used for container or user-id based fair scheduling. Also fix a problem reported by KAMEZAWA Hiroyuki (wrt allocating less-sized array for tg->cfs_rq[] and tf->se[]).
