sched: Remove unused parameter from update_deadline()

[PATCH] sched: Remove unused parameter from update_deadline()

Posted by Benjamin Tang 1 year, 3 months ago


After commit 85e511df3cec ("sched/eevdf: Allow shorter slices
to wakeup-preempt"), the 'cfs_rq' argument is no longer used
in update_deadline(). Remove it.
