| |
Since unthrottle_offline_cfs_rqs is only ever invoked when CONFIG_SMP let's pre-processor it out when SMP is not configured. This change suppresses the build error below when !CONFIG_SMP.
kernel/sched/fair.c:2055:13: warning: ‘unthrottle_offline_cfs_rqs’ defined but not used [-Wunused-function]
