At the beginning of this thread it was mentioned cdparanio uses it.
But in general we can't just rip out userland interfaces, we pretend
to have a stable userspace abi (and except for the big sysfs mess that
actually comes very close to the truth).
What we should do is to document very well what SG_DXFER_TO_FROM_DEV
is doing and that odd name that's been chosen for it. I'll prepare
a patch for that.
