Did I really say it does ? :-) Now, to the point it just makes it
much easier to reason about this setsockopt which was doing conditional
locking in some of the cases before, and some were left out, also "v"
was sometimes signed and sometimes unsigned, it's clearer now which type
is used. I've left a comment why the only special case needs to unlock
rtnl (MRT_DONE).
