Subject: sched/autogroup: Define autogroup_path() for !CONFIG_SCHED_DEBUG
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b853922613c59f68c5c0a8d25f09e1897ce841ce;p=platform%2Fkernel%2Flinux-exynos.git

sched/autogroup: Define autogroup_path() for !CONFIG_SCHED_DEBUG

Define autogroup_path() even in the !CONFIG_SCHED_DEBUG case. If
CONFIG_SCHED_AUTOGROUP is enabled the path of an autogroup has to be
available to be printed in the load tracking trace events provided by
this patch-stack regardless whether CONFIG_SCHED_DEBUG is set or not.
