Subject: [Qemu-devel] [PATCH] qemu-iotests/195: Change multiple nodes in one run
Date: Wed, 20 Sep 2017 14:15:15 +0200 [thread overview]
Message-ID: <20170920121515.1311-1-kwolf@redhat.com> (raw)
This additional check for change-backing-file makes sure that actions on
one part of the graph don't interfere with later actions elsewhere.
Suggested-by: Eric Blake <eblake@redhat.com>
