FYI, we noticed the below changes on
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched/core
commit 638476007d13534b2ed4134bf0279ef44071140b ("sched/fair: Fix the dealing with decay_count in __synchronize_entity_decay()")
It appears that your patch cause CPU usage increased a little, so that unixbench score increased.
