sched/debug: Move print_cfs_rq() declaration to kernel/sched/sched.h (6b55c965) · Commits · 戴 / test

Currently print_cfs_rq() is declared in include/linux/sched.h. However it's not used outside kernel/sched. Hence move the declaration to kernel/sched/sched.h Also some functions are only available for CONFIG_SCHED_DEBUG=y. Hence move the declarations to within the #ifdef. Signed-off-by:
