  "message": "block: support passing \u0027backing\u0027: \u0027\u0027 to \u0027blockdev-add\u0027\n\nPassing an empty string allows opening an image but not its backing\nfile. This was already described in the API documentation, only the\nimplementation was missing.\n\nThis is useful for creating snapshots using images opened with\nblockdev-add, since they are not supposed to have a backing image\nbefore the operation.\n\nSigned-off-by: Alberto Garcia \u003cberto@igalia.com\u003e\nReviewed-by: Max Reitz \u003cmreitz@redhat.com\u003e\nReviewed-by: Eric Blake \u003ceblake@redhat.com\u003e\nReviewed-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\nReviewed-by: Jeff Cody \u003cjcody@redhat.com\u003e\nSigned-off-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\n",
