Shouldn't it be documented how dm-dedup recovers from a power failure ? Since different storage devices are used for data and meta-data recovery from a power failure is nontrivial. How is it e.g. guaranteed if a data block has been made persistent (e.g. via REQ_FUA) and the refcount is increased for that data block that neither the data nor the metadata for that data block is lost if a power failure occurs ?
