[Qemu-devel] [PATCH 3/3] vpc: Do not return RAW from block_status |

vpc is not really a passthrough driver, even when using the fixed
subformat (where host and guest offsets are equal). It should handle
preallocation like all other drivers do, namely by returning
DATA | RECURSE instead of RAW.
There is no tangible difference but the fact that bdrv_is_allocated() no
longer falls through to the protocol layer.
