Subject: [PATCH] sched: remove noop function task_fork_dl
Date: Wed, 27 Nov 2019 09:03:28 -0800	[thread overview]
Message-ID: <56b066c2-90fd-4263-cf31-0a08ea44fd53@redhat.com> (raw)


task_fork_dl is an empty function used only for dl's
sched_class.task_fork.  Removing it cleans up the code a bit
and saves a function call in sched_fork.
