From c0bdfd72fbfb7319581bd5bb09b4f10979385bac Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 22 May 2023 21:50:19 +0200 Subject: [PATCH] sched/fair: Hide unused init_cfs_bandwidth() stub init_cfs_bandwidth() is only used when CONFIG_FAIR_GROUP_SCHED is enabled, and without this causes a W=1 warning for the missing prototype: kernel/sched/fair.c:6131:6: error: no previous prototype for 'init_cfs_bandwidth' The normal implementation is only defined for CONFIG_CFS_BANDWIDTH, so the stub exists when CFS_BANDWIDTH is disabled but FAIR_GROUP_SCHED is enabled.
