[Qemu-devel] [PATCH v6 9/9] iotests: Test changed Quorum filename

From: Max Reitz
Subject: [Qemu-devel] [PATCH v6 9/9] iotests: Test changed Quorum filename
Date: Mon, 16 Jan 2017 17:13:54 +0100

After drive-mirror replacing a Quorum child, the filename of the Quorum
BDS should reflect the change. This patch replaces the existing test for
whether the operation did actually exchange the BDS (which simply tested
whether the new BDS existed) by a test which examines the children list
contained in the Quorum BDS's filename as returned by query-block.

As a nice side effect of confirming that the new BDS actually belongs to
the Quorum BDS, this checks whether the filename was properly updated.
