Thanks for refatoring some of the pieces. I suspect some more can be done. In the long run, I don't think this copy-and-paste is scalable. For most of the options (integer value and do not need ns_capable()), do_tcp_setsockopt() and sock_setsockopt() can be directly called with some refactoring.
The change looks good. For this patch, Acked-by: Martin KaFai Lau <ka...@fb.com>
