Subject: [PULL 03/19] qemu-img: allow qemu-img measure --object without a filename
Date: Wed, 11 Mar 2020 14:51:57 +0100	[thread overview]
Message-ID: <20200311135213.1242028-4-mreitz@redhat.com> (raw)
In-Reply-To: <20200311135213.1242028-1-mreitz@redhat.com>

From: Stefan Hajnoczi <stefanha@redhat.com>

In most qemu-img sub-commands the --object option only makes sense when
there is a filename.  qemu-img measure is an exception because objects
may be referenced from the image creation options instead of an existing
image file.  Allow --object without a filename.
