But I'm not sure it's worth it. Increasing cb by 4 bytes shouldn't be a very big issue.
If increasing the cb by 4 bytes is ok, it would make my life easier and the code simpler. But I don't think it would also be a big issue to remove the prev pointer.
Now, if we can agree on increasing the tcp_sock by 20 bytes I'll be able to continue my work.
