The member back in struct sched_rt_entity only related to RT_GROUP_SCHED, it should not place out of RT_GROUP_SCHED, move back to RT_GROUP_SCHED. It will save a few bytes.
The 1st patch is introduce for_each_sched_rt_entity_back() & use it, it no functional changes.
The 2nd patch is init 'back' in init_tg_rt_entry, it remove the call to back when CONFIG_RT_GROUP_SCHED is disabled.
The 3rd patch is move sched_rt_entity::back to under the CONFIG_RT_GROUP_SCHED block, it will save a few bytes.
