Hi Kevin, This tries to capture your idea to add a explicit command option in qemu-io and qemu-img for user to specify "expect inconsistent data when reading image". It's stored as a BDRV_O_ flag internally, I don't know if there is a cleaner way or not.
It's depended on by image locking series because several test cases need to be updated to use this flag.
