└─>KMEM DAX: volatile-use of persistent memory
In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Support access to persistent memory as if it were RAM. This
allows easier use of persistent memory by unmodified
applications.
To use this feature, a DAX device must be unbound from the
device_dax driver (PMEM DAX) and bound to this kmem driver
on each boot.
Say N if unsure.
