From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Fri, 17 Mar 2006 17:21:15 +0900 From: Yasunori Goto Subject: [PATCH: 005/017]Memory hotplug for new nodes v.4.(generic refresh NODE_DATA()) Message-Id: <20060317163118.C641.Y-GOTO@jp.fujitsu.com> MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org Return-Path: To: Andrew Morton Cc: "Luck, Tony" , Andi Kleen , Linux Kernel ML , linux-ia64@vger.kernel.org, linux-mm List-ID: This function refresh NODE_DATA() for generic archs. In this case, NODE_DATA(nid) == node_data[nid]. node_data[] is array of address of pgdat. So, refresh is quite simple.
