Michal Prívozník (2): virdevmapper: Don't error on kernels without DM support virdevmapper: Deal with unloading dm module
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: Tested-by: Christian Ehrhardt <christian.ehrhardt@canonical.com>
