possibly. The v440 is using  a Debian 4.6.3-14 gcc, while the
T5 is using "4.4.7 20120313 (Red Hat 4.4.7-4)"

But my question from the email remains. Unless I am missing
something subtle in the code, a  struct request_sock and a 
struct sock only have the sock_common part in common. So casting
a request_sock as a struct sock may have issues?
