Subject: [Qemu-devel] [PATCH v9 07/13] iotests: prepare 124 and 257 bitmap querying for backup-top filter
Date: Mon, 26 Aug 2019 19:13:06 +0300	[thread overview]
Message-ID: <20190826161312.489398-8-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20190826161312.489398-1-vsementsov@virtuozzo.com>

After backup-top filter appearing it's not possible to see dirty
bitmaps in top node, so use node-name instead.
