Abstract: A call with respect to data for a file from an application program running on a computing device to a block-oriented file access function of an operating system running on the computing device is intercepted. A DAX file access is responsively performed with respect to a memory region of a persistent memory storing the file and an application buffer for the application program within an application memory space to which the memory region has been mapped.
