![]() The statistical analysis of the Linux bug data suggests that the Linux kernel may draw significant benefits from the continual reliability improvement efforts of its developers. We also justify and explain the statistical bug occurrence trends observed from the data, using the architecture of the Linux kernel as an anchor. To acquire this insight, we conducted an extensive analysis of the publicly available bug data on the Linux kernel over a period of seven years. An important first step in improving the reliability of an operating system is to gain insights into why and how the bugs originate, contributions of the different modules to the bugs, their distribution across severities, the different ways in which the bugs may be resolved and the impact of bug severities on their resolution times. Efforts to improve application reliability can be irrelevant if the reliability of the underlying operating system on which the application resides is not seriously considered.
