Abstract
An embodiment may include circuitry to perform option (a) and/or option (b). In option (a), the circuitry may maintain a journal to record information that is related to a transaction that may result in writing to at least one logical address and at least one physical address of the storage. The information may be recorded in the journal via an atomic operation that may be executed prior to recording, at least in part, the information in a data structure that correlates the at least one logical address to the at least one physical address. In option (b), the circuitry may maintain another data structure that indicates a correlation between at least one other physical address and the at least one logical address. The correlation may be valid prior to completion of the transaction, but the correlation may no longer be valid after the completion.
