--- Comment #25 from Jan Žižka <jan.zizka at nokia dot com> --- I have backported all three patches but true that I didn't try to test without VN enhancement. Would it help if I'd try that with our production code and the reproducers? Or anything else I could try so that you'd know if the VM enhancement should be backported also?
