Systems and methods for coordinating sync points between a non-volatile memory (“NVM”) and a file system are provided. In some embodiments, a file system can issue one or more commands to control circuitry of a NVM, which can indicate whether a transaction is journaled or non-journaled. This way, the control circuitry can maintain a list of journaled transactions and corresponding LBA(s). By keeping track of journaled transactions, the control circuitry can ensure that sync points are not prematurely erased during a garbage collection process. In addition, upon detecting device failure events, the control circuitry can roll back to sync points corresponding to one or more journaled transactions. |
