Thanks for the pointer. I looked at dm-thin for examples, but that was
not the best one. I will study all these methods more.

Thank you. Let me know if you see anything not satisfying. I will keep
testing on my side to make sure there are no obvious problems remaining.
We are also finishing a set of test case for blktests for the dm zoned
block device series. Will be submitting that soon.

Best regards.
