Hello,
This series adds support for object-map and fast-diff image features.
Patches 1 - 11 prepare object and image request state machines; patches
12 - 14 fix most of the shortcomings in our exclusive lock code, making
it suitable for guarding the object map; patches 15 - 18 take care of
the prerequisites and finally patches 19 - 20 implement object-map and
fast-diff.
Nice patchset. I did review and a testing for this patchset.
TEST:
with object-map enabled, I found a case failed:
tasks/rbd_kernel.yaml.
It failed to rollback test_img while test_img is mapped.
Thanx
Thanks,
Ilya
