Hi Andy,

Um, let's not. This really isn't something the kernel needs to solve
here at all. There's a viable userspace solution. I see that the
discussion of something finally slightly technical (as opposed to just
compliance BS) has nerd sniped you a bit, but keep in mind what the
actual overall picture is. This isn't something that needs to be done.
My little CUSE thing (which I'm happy to develop out a bit more, even)
has the intent of fulfilling a compliance checkbox and nothing more.
