Embedded linux 使用内核v5.4时，Netlink内核回复参数无效

我使用带有套接字的netlink在用户空间和内核空间之间进行通信。 我的netlink在内核v4.19上写得很好。但是当我更新内核5.4时，它不起作用。 在内核v5.4中，我收到来自内核的消息是无效参数（EINVAL），但我不知道为什么它是错误的

我还尝试打印登录回调函数，该函数在struct

genl\u ops

的

.doit

字段中注册。用户空间还发送与内核源代码中的

.cmd

字段相同的命令。但是内核可能没有调用回调函数

源代码不是公开的，但我在这里被引用（user-c/user pure.c）：

这是我的源代码日志：
