Agree with this, I don't really see much point in adding an extra
warning. There's an implicit (multi-KB though) limit as well in the
message size ;-)

I tend to think of the strings more of a debugging aid, but that's a
good point.

Perhaps we should have a macro that has the strings - similar to the
inline function I put into netlink - but if we make that a macro we can
put the strings into a separate section to be able to find them more
easily for later translation, and optionally even omit them entirely
(to satisfy the kernel tinification folks)?
