BTW things like network block device would benefit from ioctl's being standartized, too. That way, I would be able to pass ioctls across network and I would be able to create network char device and play sounds over network over it :-). Pavel
PS: How many things would break if we forced ioctls to _always_ pass
struct foo { int len; char data[len]; } ?
