Red Hat has been working on new NVFS file system

Yet another new file-system being worked on for the Linux/open-source world is NVFS and has been spearheaded by a Red Hat engineer.

NVFS aims to be a speedy file-system for persistent memory like Intel Optane DCPMM. NVFS is geared for use on DAX-based (direct access) devices and maps the entire device into a linear address space that bypasses the Linux kernel's block layer and buffer cache.

I understood some of those words.
