From f2937be5895dbae23ff66767a2fc17793e63159c Mon Sep 17 00:00:00 2001 From: Yasunori Goto <y-goto@jp.fujitsu.com> Date: Thu, 9 Mar 2006 17:33:51 -0800 Subject: [PATCH] memory hotadd: pgdat->node_present_pages fix When pages are onlined, not only zone->present_pages but also pgdat->node_present_pages should be refreshed. This parameter is used to show information at /sys/device/system/node/nodeX/meminfo via si_meminfo_node(). So, it shows strange value for MemUsed which is calculated (node_present_pages - all zones free pages).
