Subject[PATCH 1/5] sched: hide unused sched_update_scaling()
Date
From: Arnd Bergmann <arnd@arndb.de>

This function is only used when CONFIG_SMP is enabled, without that there
is no caller and no prototype:

kernel/sched/fair.c:688:5: error: no previous prototype for 'sched_update_scaling' [-Werror=missing-prototypes

Hide the definition in the same #ifdef check as the declaration.

Fixes: 8a99b6833c88 ("sched: Move SCHED_DEBUG sysctl to debugfs")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
