Subject[PATCH 1/3] sched: Move print_cfs_rq declaration to kernel/sched/sched.h
Date
Currently print_cfs_rq() is declared in include/linux/sched.h.
However its not used outside kernel/sched. Hence move the declaration to
kernel/sched/sched.h

Also some functions are only available for CONFIG_SCHED_DEBUG. Hence move
the declarations within #ifdef.
