Re: [PATCH 05/10] virDomainBlockResize: Introduce VIR_DOMAIN_BLOCK_RESIZE_CAPACITY

Allow users to easily resize 'raw' images on block devices to the full capacity of the block device. Obviously this won't work on file-backed storage (filling the remaining capacity is most likely wrong) or for formats with metadata due to the overhead.
