I'd argue with the "crazy" part. This should have been the primary interface from the start. The batched dedupe interface is the crazy one: - deduping is page size granularity at worst; performance would not be horrible even if we had to do one syscall per page - vast majority of the time it will be file size granularity Why was that batching invented in the first place?
