So I'm still not convinced this is safe, and feel a bit worried about
us possibly silently missing some things. That

   default:
      return -ENOIOCTLCMD;

is what worries me.

Blocking the ones we *know* about and understand I'm perfectly fine
with. And the SG_IO case looks fine. It's the possibly unknown users
that still worry me.
