Another not-so-technical comment.

So this is basically about improving scalability and "mount" time. This
has nothing to do with checkpointing most people are aware of.

Really, this tirm is already reserved by file-systems, things like
virtual machines where it means "freezing" the contents and doing COW
when changing the freezed blocks and guaranteeing the ability to
"roll-back" to the checkpointed data.

Please, consider an option of picking a different name. In JFFS2 a
"similar" thing was called "summaries", and even this is better than
"checkpoint", I think.
