The following patch set implements checkpointing support for
UBI. Checkpointing is an optional feature which stores the physical to
logical eraseblock relations in a checkpointing superblock to reduce
the initialization time of UBI.

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

Mostly because "checkpointing" is a buzzword. ;-)

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.

What about "Erase block indexing"?
Basically a checkpoint is an index...

Thanks,

P.s: I'm really bad in picking names.
