Thanks for this patch. I've applied the change locally, and wanted to
see the test fail first, so I've reverted the following:

Are you sure this change is really needed? Otherwise why would the test
pass even without the change?

No, after reading #62140, I'm not sure. That means the test is also wrong, which I don't understand. -- All generalizations are bad.

I don't have an LVM system to test on, but I'm pretty sure we just need to add the corresponding insmod when an LVM mapping is used. In the meantime, closing this bug, please refer to #62140 for more discussion. Best, -- Josselin Poiret
