Subject: [PATCH] sched: fix a stale comment in pick_next_task()
Date: Wed, 19 May 2021 15:37:09 +0900 [thread overview]
Message-ID: <20210519063709.323162-1-masahiroy@kernel.org> (raw)
fair_sched_class->next no longer exists since commit a87e749e8fa1
("sched: Remove struct sched_class::next field").
Now the sched_class order is specified by the linker script.
Rewrite the comment in a more generic way.
