[Qemu-devel] [PATCH v2 1/2] block: allow blockdev-backup from any source

From: John Snow
Subject: [Qemu-devel] [PATCH v2 1/2] block: allow blockdev-backup from any source
Date: Thu, 28 Jun 2018 14:00:41 -0400

In the case of image fleecing, the node we choose as the source
for a blockdev-backup is going to be both a root node AND the
backing node for the exported image. It does not qualify as a root
image in this case.

Loosen the restriction.
