Subject: [PATCH 134/260] Fix convert function to support NVMe devices
606ea6
606ea6
This is adapted from the patch at
606ea6
https://bugzilla.redhat.com/show_bug.cgi?id=1019660 , which is against
606ea6
the now very old version of convert_system_partition_to_system_disk().
606ea6
606ea6
As such, it certainly not the right thing for upstream, but should
606ea6
function for now.
