# HEAD: bbce3de72be56e4b5f68924b7da9630cc89aa1a8 sched/eevdf: Fix se->slice being set to U64_MAX and resulting crash

Fix sporadic crashes in dequeue_entities() due to ... bad math.

[ Arguably if pick_eevdf()/pick_next_entity() was less trusting
of complex math being correct it could have de-escalated a crash into a warning, but that's for a different patch. ]

Thanks,

Ingo
