Abstract:
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.
