From d475e5acd2f4679d6ce458369ee658dbd60227e9 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 11 Mar 2014 17:42:41 +0100 Subject: qcow2: Keep option in qcow2_invalidate_cache() Instead of manually building a list of all options from BDRVQcowState values just reuse the options that were used to open the image. qcow2_open() won't fully use all of the options in the QDict, but that's okay. This fixes all of the driver-specific options in qcow2, except for lazy-refcounts, which was special cased before.
