Ok, I was really hoping to avoid doing this.  Like I said, binary compatibility
is important, and changing the type will break my existing apps.  Are you
insisting that I pick a new number?

I definitely insist that you have a proper interface in the driver at the
time that it gets merged, and that probably includes a collision-free
ioctl code.

This sort of stuff is one of the issues that should be being factored in
to any decision not to publish and submit the kernel code - ABIs that
haven't been reviewed upstream may well have this sort of issue.
