For every node in the backing chain, collect its BlockGraphInfo struct using bdrv_query_block_graph_info(). Print all nodes' information, indenting child nodes and labelling them with a path constructed from the child names leading to the node from the root (e.g. /file/file). Note that we open each image with BDRV_O_NO_BACKING, so its backing child is omitted from this graph, and thus presented in the previous manner: By simply concatenating all images' information, separated with blank lines. This affects two iotests: - 065: Here we try to get the format node's format specific information. The pre-patch code does so by taking all lines from "Format specific information:" until an empty line. This format specific information is no longer followed by an empty line, though, but by child node information, so limit the range by "Child node '/file':". - 302: Calls qemu_img() for qemu-img info directly, which does not filter the output, so the child node information ends up in the output.
