[Qemu-devel] [PATCH v2 0/6] Provide additional info through qemu-img info

[Max Reitz <mreitz@redhat.com>]

qemu-img info provides only pretty general information about an image.
For any image format, there might be specific options which cannot be
represented in a universal way; for instance, qcow2 provides the
compatibility and lazy_refcount options whose values are certainly
interesting but currently cannot be output by qemu-img info.

Therefore, this series adds a new ImageInfoSpecific union type to
ImageInfo and BlockDriverInfo which may be used by block drivers as a
template for new types dedicated to the specific information they can
provide. It also adds support to qemu-img info and qemu-io -c info to
print the content of these specific structures.

v2:
 - following Eric's recommendation: changed the representation of the
   format specific information from an uninterpreted blobbed string to a
   union of format specific types

Max Reitz (6):
  qapi: Add ImageInfoSpecific type
  block: Add ImageInfoSpecific to BlockDriverInfo
  block/qapi: Human-readable ImageInfoSpecific dump
  qcow2: Add support for ImageInfoSpecific
  qemu-iotests: Discard specific info in _img_info
  qemu-iotests: Additional info from qemu-img info
