The latest one is NOVA, as far as I can see. But, frankly speaking, I believe that we need in new hardware paradigm/architecture and new OS paradigm for the next generation of NVM memory. The DAX is simple palliative, temporary solution. But, from my point of view, pmem-native fs is also not good direction because, anyway, memory subsystem will be affected significantly. And, finally, evolution of memory subsystem will reveal something completely different that we can imagine right now. Thanks, Vyacheslav Dubeyko.
