Yes, I don't like that at all either. I almost wonder if we should
use an entirely different format after opcode and flags, although
I suspect fd would be nice to have in the same spot as well.
On a related note: I think it really should have a generic cmd
dispatching mechanism like ioctls have, preferably even enforcing
the _IO* mechanism.
