Sounds cool.
A few questions, if you have the time:

* Do you think that there is only 1 data corruption bug in dm snapshot
and that the code is otherwise good (data consistency wise)?

* Is dm-snapshot being actively developed?

* Which organization/person is the main developer on dm-snapshot?

I'd be more than happy to test improvements to dm-snapshot.
Is this supposed to be one?

What's the codebase that this patch applies to?
