[Qemu-block] [PATCH v11 30/31] block: BDS options may lack the "driver"


From: Max Reitz
Subject: [Qemu-block] [PATCH v11 30/31] block: BDS options may lack the "driver" option
Date: Sat, 6 Oct 2018 01:40:22 +0200

When BDSs are created by qemu itself (e.g. as filters in block jobs),
they may not have a "driver" option in their options QDict.  When
generating a json:{} filename, however, it must always be present.
