Yeah, I guess I can try reviewing it this way too and address each ioctl
separately. You can try splitting later so that we don't waste time now.
It would be good to have it split eventually, though, so that it is more
palatable for other rewiewers too...

... provided the functionality is not too intertwined to make a split
actually worse than a single big patch.

Thx.
