[Qemu-block] [PULL 26/33] qcow2: Store data file name in the image |
|

Fri, 8 Mar 2019 13:58:16 +0100 |
Rather than requiring that the external data file node is passed
explicitly when creating the qcow2 node, store the filename in the
designated header extension during .bdrv_create and read it from there
as a default during .bdrv_open.
