From 366e7ad6ba5f4cb2ffd0b7316e404d6ee9c0f401 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 26 Aug 2021 10:47:09 +0200 Subject: [PATCH] sched/fair: Mark tg_is_idle() an inline in the !CONFIG_FAIR_GROUP_SCHED case MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
