From a5002d53029df4d7ebaf87c821b3dc07b65e5e52 Mon Sep 17 00:00:00 2001 From: John Snow Date: Mon, 14 Dec 2015 14:55:16 -0500 Subject: block/qapi: allow best-effort query For more complex BDS trees that can be created under normal circumstances, we lose the ability to issue query commands because of our inability to re-construct the absolute filename. Instead, omit this field when it is a problem and present as much information as we can. This will change the expected output in iotest 110, where we will now see a json filename and the lack of an absolute filename instead of an error.
