I do not like this at all.
Socket option implementations should not change their behavior or what
datastructures they consume or return just because the socket happens
to be a kernel socket.
I'm not applying this series, sorry.
Also, your patch series lacked an intial "PATCH 0/N" posting, so you
could at least spend the time to discuss this patch series at a high
level and explain your overall motivations.
