Abstract
A computer-implemented method, a computer program product, and a computer system for journaling on an appendable non-volatile memory module. A kernel receives a request for a write operation of a file on a disk. The kernel instructs a memory management unit to perform an access control list verification. The memory management unit determines whether a user associated with the write operation is permitted to write a filesystem journal onto a non-volatile dual in-line memory module, by performing the access control list verification. The memory management unit writes the filesystem journal onto the non-volatile dual in-line memory module, in response to that the user associated with the write operation is permitted to write the filesystem journal. The kernel writes the file onto the disk.
