What we discussed was on a patch of mine fixing "if (!extack->_msg)" to "if (extack && !extack->_msg)". I never proposed a new macro wrapper (you did), but I didn't do it at the time because it was a patch for "net", and I forgot to put a reminder for the next net->net-next merge. https://lore.kernel.org/netdev/20220822182523.6821e...@kernel.org/ And from there, out of sight, out of mind.
