[PATCH -next] mm/page_alloc: Mark some symbols with static keyword

From: Zou Wei
Date: Mon Nov 16 2020 - 03:51:33 EST


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?
