[Qemu-devel] [Bug 1770859] [NEW] qemu-img compare -m option is missing

[Коренберг Марк]

Public bug reported:

Comparing images using multiple streams (like qemu-img convert) maybe
effectively sped up when one of the images (or both) is RBD. qemu-img
convert does it's job perfectly while converting. Please implement the
same for image comparison. Since operations are read-only, -W is
useless, but may be introduced as well for debugging/performance
purposes.
