From bd7c41765b9afa93a7f1a42e1ee353282230e2b7 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 4 Aug 2016 14:09:07 +0200 Subject: [PATCH] block/qdev: Let 'drive' property fall back to node name If a qdev block device is created with an anonymous BlockBackend (i.e. a node name rather than a BB name was given for the drive property), qdev used to return an empty string when the property was read. This patch fixes it to return the node name instead.
