Subject: [PATCH] sched/core: Optimize sched_core_next()
Date: Mon, 25 Apr 2022 01:08:14 +0800 [thread overview]
Message-ID: <1650820094-27165-1-git-send-email-CruzZhao@linux.alibaba.com> (raw)
As there is __node_2_sc() defined before, just use it instead of
container_of() in function sched_core_next().
