From: Dietmar Eggemann Date: Wed, 26 Feb 2014 11:19:33 +0000 (+0000) Subject: sched: Put rq's sched_avg under CONFIG_FAIR_GROUP_SCHED X-Git-Tag: v3.15-rc1~116^2~9 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f5f9739d7a0ccbdcf913a0b3604b134129d14f7e;p=pandora-kernel.git sched: Put rq's sched_avg under CONFIG_FAIR_GROUP_SCHED The struct sched_avg of struct rq is only used in case group scheduling is enabled inside __update_tg_runnable_avg() to update per-cpu representation of a task group. I.e. that there is no need to maintain the runnable avg of a rq in the !CONFIG_FAIR_GROUP_SCHED case. This patch guards struct sched_avg of struct rq and update_rq_runnable_avg() with CONFIG_FAIR_GROUP_SCHED. There is an extra empty definition for update_rq_runnable_avg() necessary for the !CONFIG_FAIR_GROUP_SCHED && CONFIG_SMP case. The function print_cfs_group_stats() which prints out struct sched_avg of struct rq is already guarded with CONFIG_FAIR_GROUP_SCHED.
