Performance and protection in the ZoFS user-space NVM file system

Non-volatile memory (NVM) can be directly accessed in user space without going through the kernel. This encourages several recent studies on building user-space NVM file systems. However, for the sake of file system protection, none of the existing file systems grant user-space file system libraries with direct control over both metadata and data of the NVM, leaving fast NVM resources underexploited.
