Hi,
The following series adds two parameters to qemu-img map:
1. start-offset: mapping starting offset.
2. max-length: the length of the mapping.
These parameters proved useful when mapping large disk spread across
long store file chains. It allows us to bound the execution time of each
qemu-img map execution as well as recover from failed mapping
operations. In addition the map operation can divided to
multiple independent tasks.
V2 changes:
1. add error reporting to cvtnum.
2. add image length validation in img_map.
3. rebase over QEMU 5.0.
It's better to post a v2 as a new top-level thread rather than buried
in-reply-to the v1 thread; among other things, burying a reply can cause
automated patch tooling to miss the updated series.
But since I see it, I'll review.
