Hm. I guess you could even have both?

	struct genl_ops *ops;
	struct genl_ops_ext *extops;

and then search both arrays, no need for memcpy/pointer assignment?

Yup, both should work quite nicely, too. No reason to force one or the
other.

Indeed.

Extra n_ops_ext should be fine, I think I can make n_ops a u8 in 
the first place, since commands themselves are u8s. And 0 is commonly
unused.

True. I'm not really worried about the extra pointer in the *family*
though, there aren't really all that many families :)
