名称描述
try_online_nodeUsers of this function always want to online/register the node
add_memory_resourceNOTE: The caller must call lock_device_hotplug() to serialize hotplug* and online/offline operations (triggered e.g. by sysfs).* we are OK calling __meminit stuff here - we have CONFIG_MEMORY_HOTPLUG
