nbd/client: Report offsets in bdrv_block_status It is desirable for 'qemu-img map' to have the same output for a file whether it is served over file or nbd protocols. However, ever since we implemented block status for NBD (2.12), the NBD protocol forgot to inform the block layer that as the final layer in the chain, the offset is valid; without an offset, the human-readable form of qemu-img map gives up with the unhelpful: $ nbdkit -U - data data="1" size=512 --run 'qemu-img map $nbd' Offset Length Mapped to File qemu-img: File contains external, encrypted or compressed clusters. The --output=json form always works, because it is reporting the lower-level bdrv_block_status results directly rather than trying to filter out sparse ranges for human consumption - but now it also shows the offset member. With this patch, the human output changes to: Offset Length Mapped to File 0 0x200 0 nbd+unix://?socket=/tmp/nbdkitOxeoLa/socket This change is observable to several iotests.
