  If you're talking about checks in sysctl, I believe it should be
another patch for sysctl only, and I'm going to push it via -mm tree.

  the devision by zero exists in inet_connection_socket.c, and must be
fixed for sure because the situation with the same min and max port
numbers in sysctl are possible and not prohibited.

Cheers!
