Only that I want to write this tcp_sendpage function myself for custon stack. Then create a cleaner api for your custom stack.Refrain from littering the in kernel methods which are tried and tested.Hooking is one option but it is *not* simple to hook networking stackespecially at tcp layer. I suggest you try developing custom api for your stack if it has to coexist with the in kernel tcp/ip stack.e.g ssize_t tcp_sendpage_custom(struct socket *sock, struct page*page, int offset, size_t size, int flags) See how the original function uses the struct page * , follow on same lines.
