Since its inception, the DAX mechanism (which provides for direct access to files stored on persistent memory) has been seen as somewhat experimental and incomplete. At the 2019 Linux Storage, Filesystem, and Memory-Management Summit, Dan Williams ran a session where he said that perhaps the time has come to end that experiment. Some of the unimplemented DAX features may never actually need to be implemented, and it might just be possible to declare DAX finished. But first there are a few more details to take care of.
