  "message": "block/blkio: retry blkio_connect() if it fails using `fd`\n\nlibblkio 1.3.0 added support of \"fd\" property for virtio-blk-vhost-vdpa\ndriver. In QEMU, starting from commit cad2ccc395 (\"block/blkio: use\nqemu_open() to support fd passing for virtio-blk\") we are using\n`blkio_get_int(..., \"fd\")` to check if the \"fd\" property is supported\nfor all the virtio-blk-* driver.\n\nUnfortunately that property is also available for those driver that do\nnot support it, such as virtio-blk-vhost-user.\n\nSo, `blkio_get_int()` is not enough to check whether the driver supports\nthe `fd` property or not. This is because the virito-blk common libblkio\ndriver only checks whether or not `fd` is set during `blkio_connect()`\nand fails with -EINVAL for those transports that do not support it\n(all except vhost-vdpa for now).\n\nSo let\u0027s handle the `blkio_connect()` failure, retrying it using `path`\ndirectly.\n\nFixes: cad2ccc395 (\"block/blkio: use qemu_open() to support fd passing for virtio-blk\")\nSuggested-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\nSigned-off-by: Stefano Garzarella \u003csgarzare@redhat.com\u003e\nMessage-id: 20230727161020.84213-3-sgarzare@redhat.com\nSigned-off-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\n",
