Subject: [PATCH 114/198] Fix convert function to support NVMe devices
|
|
|
|
This is adapted from the patch at
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1019660 , which is against
|
|
the now very old version of convert_system_partition_to_system_disk().
|
|
|
|
As such, it certainly not the right thing for upstream, but should
|
|
function for now.
|
|
|
|
Resolves: rhbz#1019660
