netlink init order

BTW, is there any reason why init_netlink_dev() is not a module_init()?

We have
int init_module(void)
{
        printk(KERN_INFO "Network Kernel/User communications module 0.04\n");
        return init_netlink();
}

void cleanup_module(void)
{
        int i;

        for (i = 0; i < ARRAY_SIZE(entries); i++)
                devfs_remove("netlink/%s", entries[i].name);
        for (i = 0; i < 16; i++)
                devfs_remove("netlink/tap%d", i);
        devfs_remove("netlink");
        unregister_chrdev(NETLINK_MAJOR, "netlink");
}

in netlink_dev.c and

#ifdef CONFIG_NETLINK_DEV
        init_netlink();
#endif
        return 0;
}

in the end of netlink_proto_init(), which is core_initcall.
