如何在linux-kernel4.18上用register_security注册一个安全模块？

struct security_module {
    struct module *owner;
    int (*security_func1)(...);
    void (*security_func2)(...);
    // 其他函数指针和数据成员
};

static struct security_module my_security_module = {
    .owner = THIS_MODULE,
    .security_func1 = my_security_func1,
    .security_func2 = my_security_func2,
    // 其他函数指针和数据成员的初始化
};

static int __init my_security_module_init(void) {
    int ret = register_security(&my_security_module);
    if (ret != 0) {
        printk(KERN_ERR "Failed to register security module\n");
        return ret;
    }
    return 0;
}

static void __exit my_security_module_exit(void) {
    unregister_security(&my_security_module);
}

$ make
$ insmod security_module.ko
