Me, I don't really care either way.

I suppose the NBD_DO_IT ioctl will need to remain, since handing an fd
through a write in a totally unrelated file is going to be *very* ugly.
Other than that, I guess moving communication between client and server
to sysfs entries makes more sense.

But then, I don't generally tread in your side of the syscall :-)
