Hi all!
We need to load bitmaps from parallels image in our product.
So here is a feature.
v2:
01: tweak commit message, add r-bs by Eric and Denis
02: tweak wording by Denis's suggestions
03: new, suggested by Denis
04: rebase on 03, add several error checking,
convert l1 table to cpu from small-endian,
allow loading several bitmaps
06: add copyright, drop "/work/mega"
Vladimir Sementsov-Ogievskiy (6):
qcow2-bitmap: make bytes_covered_by_bitmap_cluster() public
parallels.txt: fix bitmap L1 table description
block/parallels: BDRVParallelsState: add cluster_size field
parallels: support bitmap extension for read-only mode
iotests.py: add unarchive_sample_image() helper
iotests: add parallels-read-bitmap test
