You add an ioctl yet fail to justify _why_ you need/want that ioctl, and
you don't document it at all?  Come on, you know better than that, no
one can take a patch that has no changelog comments at all like this :(

Also, I _REALLY_ don't want to add any ioctls to the UIO interface, so
you had better have a really compelling argument as to why this is the
_ONLY_ way you can solve this unknown problem by using such a horrid
thing...
