We conducted a comprehensive study of Linux file system evolution by analyzing eight years of changes across 5,079 patches, deriving numerous new (and sometimes surprising) insights into the file-system development process. Our observations should be useful to file-system developers, systems researchers, and tool builders. Careful study of these results should bring about a new generation of more robust, reliable, and performant file systems.
