From: Zou Wei <zou_wei@xxxxxxxxxx> Subject: mm/page_alloc: mark some symbols with static keyword Fix the following sparse warnings: mm/page_alloc.c:3040:6: warning: symbol '__drain_all_pages' was not declared. Should it be static? mm/page_alloc.c:6349:6: warning: symbol '__zone_set_pageset_high_and_batch' was not declared. Should it be static?
