Hi Michal,
I know from the discussions on the patches that there likely will be
some changes before this is complete.
Nevertheless I did some testing with them already.

In particular since I was reporting this to also affect system
containers that have device-mapper
loaded as module and in /proc/devices but no /dev/mapper/control
exposed. I wanted to
give your patches a try for this use case as well since I wasn't sure
anyone else would.

I can confirm that functionally your patches applied on top of 6.6 (as
we work on it for
Debian&Ubuntu) make it work again. Therefore:
