Ucore is a small operating system for learning, the " Sparrow" contains the virtual memory management, process management, processor scheduling, synchronization mutually exclusive, inter-process communication, file system and other major kernel functions, the total amount of kernel code ( C+ asm) no more than 5K lines. Fully embodies the " small" the guiding ideology. This is ucore Lab 6: File system. By completing this experiment, hoping to achieve the following objectives: To understand the basic file system system calls the implementation method understand the organization of a node-based index of the Simple FS file system design and implementation understand the abstraction layer-VFS file system design and achieved. File, including source code and test instructions.
