Subject: sched/fair: Mark tg_is_idle() an inline in the !CONFIG_FAIR_GROUP_SCHED case
X-Git-Tag: accepted/tizen/unified/20230118.172025~6570^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=366e7ad6ba5f4cb2ffd0b7316e404d6ee9c0f401;p=platform%2Fkernel%2Flinux-rpi.git

sched/fair: Mark tg_is_idle() an inline in the !CONFIG_FAIR_GROUP_SCHED case

It's not actually used in the !CONFIG_FAIR_GROUP_SCHED case:

  kernel/sched/fair.c:488:12: warning: ‘tg_is_idle’ defined but not used [-Wunused-function]

Keep around a placeholder nevertheless, for API completeness. Mark it inline,
so the compiler doesn't think it must be used.

Fixes: 304000390f88: ("sched: Cgroup SCHED_IDLE support")
