A hurd ioctl has to also have something which documents the exact structure
layout in a way that the library can use to reformat it into a Mach
message. That's what the _IOT_foo thing would be. Since it's missing, the
_IOW call fails.
Some ioctls can't be represented, for various reasons, and require special
treatment in the library itself.
