When memory pressure triggers direct memory reclaim, a slabs age and delay should not prevent it from being freed. This patch ensures these values are ignored, allowing an empty slab to be freed in this code path no matter the value of its age and delay. This prevents needless scanning of the partial slabs and has been observed to significantly reduce the total cpu usage. In addition, it should allow for snappier reclaim under memory pressure.
