Emulating Persistent Memory in the Linux Kernel with Different Page Sizes

With the implementation of system-ram operational mode [1] of devdax, you can just use normal linux interfaces for allocation of huge pages [2]. Those then can be seamlessly utilized by most memory allocators, with no need to modify anything.

libvmmalloc has been superseded by libmemkind [3], which better allows you to control the behavior of what I just described.
