I'm not too happy about making this part of ImageInfoSpecificQCow2.
Two reasons for this: First, it's eventually part of ImageInfo, which
is defined as "Information about a QEMU image file", but this option
cannot be set in the image file itself but is only a run-time option.
That's a valid point. Now that I think of it, do we actually have a way
to retrieve the sizes of the L2 and refcount caches? I think cache-size,
l2-cache-size, and refcount-cache-size are already write-only values.
No, in fact we don't. Well, except for if you manage to retrieve the
JSON filename for the qcow2 BDS, it should be part of that. :-P
And I just noticed, passing that option will result in qemu returning
the JSON filename when queried:
$ qemu-img info "json:{'l2-cache-size':65536,'file.filename':'test.qcow2'}"
image: json:{"driver": "qcow2", "l2-cache-size": 65536, "file":
{"driver": "file", "filename": "test.qcow2"}}
