+ This feature allows to estimate the amount of user pages that have

+ be useful to tune memory cgroup limits and/or for job placement
+ within a compute cluster.

+ help
+ Device memory hotplug support allows for establishing pmem,
+ or other device driver discovered memory regions, in the
+ memmap. This allows pfn_to_page() lookups of otherwise
+ "device-physical" addresses which is needed for using a DAX
+ mapping in an O_DIRECT operation, among other things.
