[$] The ZUFS zero-copy filesystem

At the 2018 Linux Storage, Filesystem, and Memory-Management Summit(LSFMM), Boaz Harrosh presented his zero-copy user-mode filesystem (ZUFS).It is both a filesystem in its own right and a framework similar to FUSE forimplementing filesystems in user space. It is geared toward extremely low latency andhigh performance, particularly for systems using persistent memory.
