ENOTTY is used by several non-serial devices (or file systems) to
object to an unrecognized ioctl command. There's also ENOIOCTLCMD
(apparently supposed to be a non-user errno, but i don't see where it
gets changed to something else) and EINVAL. I'm not sure what the
rationale is for choosing among them; perhaps someone would elucidate?
