Subject: [PATCH 0/2] sched: Return NULL when entity isn't a task
Date: Fri, 1 Dec 2023 10:27:02 +0800 [thread overview]
Message-ID: <20231201022704.3526377-1-yajun.deng@linux.dev> (raw)
If the entity isn't a task, return the task struct is meaningless.
Return NULL when entity isn't a task that makes the code more concise.
Yajun Deng (2):
sched/fair: Return NULL when entity isn't a task in task_of()
sched/rt: Return NULL when rt entity isn't a task in rt_task_of()
