Subject: [RFC PATCH v5 03/19] memory-hotplug: store the node id in acpi_memory_device
Date: Fri, 27 Jul 2012 18:27:16 +0800 [thread overview]
Message-ID: <50126D04.6060707@cn.fujitsu.com> (raw)
In-Reply-To: <50126B83.3050201@cn.fujitsu.com>
The memory device has only one node id. Store the node id when
enable the memory device, and we can reuse it when removing the
memory device.
