From bbc8ea98bc8a2ba8174d106184f3089248d5ec5d Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 29 Sep 2016 18:47:03 +0200 Subject: block-backend: Remember if attached device is non-qdev Almost all block devices are qdevified by now. This allows us to go back from the BlockBackend to the DeviceState. xen_disk is the last device that is missing. We'll remember in the BlockBackend if a xen_disk is attached and can then disable any features that require going from a BB to the DeviceState. While at it, clearly mark the function used by xen_disk as legacy even in its name, not just in TODO comments.
