In this project we develop a stackable file system that allows you to control which VFS operations are passed to userland. This way we only pass the operations that are needed and no more. We also control how much information we pass to userland (just file name, just operation, full directory pathname, etc.). Again, this is designed to reduce the amount of data that needs to be copied to userland. For further efficiency, we communicate with a userland component using either user/kernel shared memory or the Linux netlink socket. In userland, we have a library wrapper can be integrated into any application, and daemon driver that can act as a file server. With these tools, users can experiment with file system extensions without having to know kernel internals or become file system hackers.
