Before anybody spends more time with this patchset: this is a big feature and quite intrusive to several btrfs subsystems. Currently it's on hold as it requires finishing the design phase, it's still only the in-memory backend and before we claim in-band dedupe, the persistent hash tree needs to be at least drafted or prototyped. At this point there are several features that are in a more complete state so they get preferred when it comes to merging. I would have to look up what was agreed long time ago as merging plan, but at this point this series would require a lot of work.
