Abstract:
We conduct a comprehensive study of file-system code
evolution. By analyzing eight years of Linux file-system
changes across 5079 patches, we derive numerous new
(and sometimes surprising) insights into the file-system
development process; our results should be useful for both
the development of file systems themselves as well as the
improvement of bug-finding tools.
