修改/net/ipv4/tcp_output.c#L，1823行 tcp_snd_wnd_test函数大括号后} 换行添加EXPORT_SYMBOL(tcp_snd_wnd_test);
/ Does at least the first segment of SKB fit into the send window? / static bool tcp_snd_wnd_test(const struct tcp_sock tp, const struct sk_buff skb, unsigned int cur_mss) { u32 end_seq = TCP_SKB_CB(skb)->end_seq;
} EXPORT_SYMBOL(tcp_snd_wnd_test);
