Subject: [PATCH v2 0/2] sched/rt: Move sched_rt_entity::back to CONFIG_RT_GROUP_SCHED
Date: Wed, 5 Jun 2024 21:35:55 +0800 [thread overview]
Message-ID: <20240605133557.2984-1-yajun.deng@linux.dev> (raw)
The 'back' member 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.
v1 -> v2:
- introduce rt_se_back() helper function.
Yajun Deng (2):
sched/rt: Use 'back' only if CONFIG_RT_GROUP_SCHED is enabled
sched/headers: Move sched_rt_entity::back to under the
CONFIG_RT_GROUP_SCHED block
