Arnd sent the v1 of the series in July, and it was bogus. So with a
little help from claude-sonnet I built up the missing ioctls tests and
tried to figure out a way to apply Arnd's logic without breaking the
existing ioctls.

The end result is in patch 3/3, which makes use of subfunctions to keep
the main ioctl code path clean.

Arnd, I kept your From: and SoB fields, please shout if you are unhappy.

Jiri, checkpatch.pl complains about my co-develop tag. Did we get some
consensus for AI-assisted tag?
