[PATCH] drain_node_page(): Drain pages in batch units
drain_node_pages() currently drains the complete pageset of all pages. If there are a large number of pages in the queues then we may hold off interrupts for too long. Duplicate the method used in free_hot_cold_page. Only drain pcp->batch pages at one time.
