But for now I'd really prefer to stop moving the goalpost further and
further.

Then, why not kill this code?

I think we should eventually do that, and I've indeed tested a patch
that is only cosmetically different.  I wasn't really convinced we
should do it in this series, but if there is consensus that we should
do it now I can respin the series with a patch like this included.

I'd defer it to a separate patchset. Because as much as the change to
disallow LOOP_CLR_FD ioctl for used loop device makes sense, I'm not sure
there isn't some framework using loop devices somewhere which relies on
this just getting magically translated to setting LO_AUTOCLEAR flag. So IMO
this has a big potential of userspace visible regression and as such I'd
prefer doing it separately from the bugfixes.
