This check exists before git history, at that time 'sk' could be NULL, hence 'np', so it does not mean it is still necessary now. I looked at all callers of ip6_xmit(), I don't see how it is called with a non-full socket, neither 'sk' could be NULL after commit b30bd282cbf5c46247a279a2e8d2aae027d9f1bf ("[IPV6]: ip6_xmit: remove unnecessary NULL ptr check"). Thanks.
