From ad69444e75d77981291ccf807f48d81e8fca010f Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Fri, 24 Feb 2017 14:59:45 -0800 Subject: [PATCH] mm/page_alloc.c: remove redundant init code for ZONE_MOVABLE arch_zone_lowest/highest_possible_pfn[] is set to 0 and [ZONE_MOVABLE] is skipped in the loop. No need to reset them to 0 again. This patch just removes the redundant code.
