It's a shame to expose new ABI bits that we expect to change to
mainline. Getting rid of obsolete interfaces is next to impossible so
the introduction of new interfaces really does warrant serious

Can we come up with a scheme to keep the new ioctls introduced by this
driver from leaking over into distro-land before they get reworked?
Like preemptively adding a deprecation printk?
