[clug] Is there a NVMe equivalent to the Fusion-IO 'Virtual Storage Layer'?

In 2011, Fusion-IO & Princeton produced a driver that extended RAM with Flash memory on the PCIe bus.
This avoided page faults entirely - calls didn’t go through the disk drive stack - making this blindingly fast.

I’ve found the ‘nmve’ driver, but think that only maps the SSD as a disk drive, not as ‘extended memory’.

Is there a modern equivalent for M.2 PCIe / NVMe SSD’s?
