This series adds "compressed" field to the output of "qemu-img map"
command, specifying whether or not data block is compressed. Only
JSON output mode is affected. With this applied, output looks like so:
# qemu-img create -f qcow2 img.qcow2 192K
# qemu-io -c "write -c -P 0xaa 0 64K" img.qcow2
# qemu-io -c "write -P 0xbb 64K 64K" img.qcow2
# qemu-img map --output=json img.qcow2
[{ "start": 0, "length": 65536, "depth": 0, "present": true, "zero": false,
"data": true, "compressed": true},
{ "start": 65536, "length": 65536, "depth": 0, "present": true, "zero": false,
"data": true, "compressed": false, "offset": 393216},
{ "start": 131072, "length": 65536, "depth": 0, "present": false, "zero": true,
"data": false, "compressed": false}]
Only formats supporting compression are affected (qcow, qcow2).
Andrey Drobyshev (3):
block: add BDRV_BLOCK_COMPRESSED flag for bdrv_block_status()
qemu-img: map: report compressed data blocks
qemu-iotests: update expected tests output to contain "compressed"
field
