Re: [PATCH v6 00/10] Tighten qemu-img rules on missing backing format

v5 was here: https://lists.gnu.org/archive/html/qemu-devel/2020-04/msg00679.html In v6: - add a few more patches - change qcow semantics based on several iterations of mailing list debates on what behavior is easiest to support - add iotesting that a probed raw file cannot be committed into - instead of recording an implicit probed raw file, instead we record only a non-raw file - rebase to a few more affected iotests, plus s/5.0/5.1/ Yes, I know this is really short notice to make it in before feature freeze for 5.1 (removal in 6.0), so it may end up slipping into 5.2 (removal in 6.1); but we'll see how things go.
