I don't understand at all. What exactly are you trying to create here?
And don't use a module parameter for anything, you are limiting yourself
to only one "device" that way, as well as preventing any distro from
ever using your code.
What's wrong with just using the device mapper interface in the kernel
for whatever you are trying to do, instead of creating a new user api?
