[Qemu-devel] [PATCH 0/3] 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 an info-string field to ImageInfo resp.
info_string to BlockDriverInfo which may be used by block drivers to
hand an uninterpreted string to the user. It also adds support to
qemu-img info and qemu-io -c info to dump that field's value.

Max Reitz (3):
  block: Additional info string in ImageInfo and BDI
  qemu-iotests: info-string filter in _img_info
  qemu-iotests: Additional info from qemu-img info
