Project 5: File System

Until project4, you have implemented the core features of modern OSes including memory, multi-threading, and scheduling. In Project 5, you will focus on implementing the file system, the abstraction of disk.

This project will involve introducing page cache for caching a file contents, and developing a fast file system with journaling to ensure data integrity and recoverability after a system crash or failure.
