Subject: [Qemu-devel] [PULL 28/69] qcow2: Allow creation with refcount order != 4
Date: Fri, 27 Feb 2015 18:18:26 +0000 [thread overview]
Message-ID: <1425061147-1411-29-git-send-email-stefanha@redhat.com> (raw)
In-Reply-To: <1425061147-1411-1-git-send-email-stefanha@redhat.com>
From: Max Reitz <mreitz@redhat.com>
Add a creation option to qcow2 for setting the refcount order of images
to be created, and respect that option's value.
This breaks some test outputs, fix them.
