From: zhong jiang <zhongjiang@xxxxxxxxxx> Subject: mm/vmstat.c: walk the zone in pageblock_nr_pages steps when walking the zone, we can happens to the holes. we should not align MAX_ORDER_NR_PAGES, so it can skip the normal memory. In addition, pagetypeinfo_showmixedcount_print reflect fragmentization. we hope to get more accurate data. therefore, I decide to fix it.
