From: Yue Hu <huy...@yulong.com> Currently, the macro sched_debug_enabled has same function as sched_debug() with return false for !SCHED_DEBUG. And sched_debug() is a wapper of variable sched_debug_enabled for SCHED_DEBUG. We can use the sched_debug() for all cases. So, let's remove the unnecessary marco, also use sched_debug() in sched_domain_debug() for code consistency.
