From 1d7732b94984ddc61de2332723176af3b208993d Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Tue, 18 Feb 2014 11:34:00 -0500 Subject: [PATCH 46/74] 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.
