Subject: [PATCH v2 3/4] qemu-img: allow qemu-img measure --object without a filename
Date: Thu,  9 Jan 2020 11:10:11 +0000
Message-ID: <20200109111012.559052-4-stefanha@redhat.com> (raw)
In-Reply-To: <20200109111012.559052-1-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.
