Subject: [PATCH] sched/deadline: remove the param struct rq in
 pick_next_dl_entity()
Message-ID: <20201022143200.GA237517@rlk>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

we can get the next dl_entity just from struct dl_rq,
and do not need the param struct rq.
So remove it.
Like the change: https://lkml.org/lkml/2020/9/29/2030
