I suggest the following: QED_CF_BACKING_FORMAT_RAW = 0x1 When set, the backing file is a raw image and should not be probed for its file format. The default (unset) means that the backing image file format may be probed. Now the backing_fmt_{offset,size} are no longer necessary.
Should it not be an incompatible option? If the backing disk starts with a format magic, it will be probed by an older qemu, incorrectly.
