Why would anyone use ZUFS since there is a persistent memory filesystem available that is simpler and that performs significantly better, namely NOVA?

IMO, the interesting bit here is the zero-copy, fast transport between userland and kernel. Layering this on top of pmem is neat (and fits Boaz requirements), but a lot of the concepts that Boaz is using here could make for a potential foundation for a better-performing replacement for FUSE.

Apart from the handwaving bits that don't actually work ;-)
