Subject: [PATCH v7 0/3] sched/rt: Move sched_rt_entity::back to CONFIG_RT_GROUP_SCHED
Date: Mon, 9 Oct 2023 20:22:41 +0800 [thread overview]
Message-ID: <20231009122244.2394336-1-yajun.deng@linux.dev> (raw)
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.
Yajun Deng (3):
sched/rt: Introduce for_each_sched_rt_entity_back() & use it
sched/rt: Init 'back' in init_tg_rt_entry
sched/headers: Move sched_rt_entity::back to under the
CONFIG_RT_GROUP_SCHED block
