I see the same warning here, gcc (Debian 4.7.2-5) 4.7.2.
Actually this function *is* used a bit further in the same file in
nfnetlink_rcv_msg().
But gcc complains for some reason of which I don't even have the
slightest idea. However, if you declare the above function "static
inline..." the warning is gone.

And it even explains why gcc complains.
Thanks.
