Um... The socket in question could be an AF_INET6 socket, not an AF_INET4
socket - I presume it will work in that case.  If so:

Yes, the implementation of that sockopt, including the inet_sock
structure where these options are set is shared between ipv4 and ipv6.

Great!  Could you note that either in the patch description or in the
kerneldoc attached to the function?

Thanks,
