It seems like there's a few more places to fix in this regard?

kernel/sched/fair.c:static u64 __sched_period(unsigned long nr_running)
kernel/sched/sched.h: unsigned long dl_nr_running;
kernel/sched/core.c:unsigned long nr_iowait_cpu(int cpu)
kernel/sched/core.c:unsigned long nr_iowait(void)
kernel/sched/loadavg.c: long nr_active, delta = 0;
kernel/sched/sched.h: unsigned long rt_nr_migratory;
kernel/sched/sched.h: unsigned long rt_nr_total;
kernel/sched/sched.h: unsigned long rt_nr_boosted;
kernel/sched/sched.h: unsigned long dl_nr_running;
kernel/sched/sched.h: unsigned long dl_nr_migratory;
kernel/sched/sched.h: unsigned long nr_uninterruptible;
