[Qemu-devel] [PATCH v2] blockdev: loosen restrictions on drive-backup source node

2019-05-21 Thread John Snow
We mandate that the source node must be a root node; but there's no reason I am aware of that it needs to be restricted to such. In some cases, we need to make sure that there's a medium present, but in the general case we can allow the backup job itself to do the graph checking. This patch helps
