(arch_register_node() for ia64) Cc: linux-ia64@vger.kernel.org, Linux Kernel ML , linux-mm , Andrew Morton X-Mailer-Plugin: BkASPil for Becky!2 Ver.2.063 Message-Id: <20060308214141.0044.Y-GOTO@jp.fujitsu.com> MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit X-Mailer: Becky! ver. 2.24.02 [ja] Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1970 Lines: 62 This is to create sysfs file for new node. It adds arch specific functions 'arch_register_node()' and 'arch_unregister_node()' to IA64 to call the generic function 'register_node()' and 'unregister_node()' respectively. (Each arch defines like sysfs_nodes[] to describe its nodes topology. I'm not sure they can be merged as generic code.)
