Who Writes the Bugs? A Deeper Look at 125,000 Kernel Vulnerabilities
Summary
This Part 2 analysis deepens the kernel-bug investigation by examining who writes buggy code, when they write it, and who catches bugs fastest. It reports that 117 super-reviewers fix bugs much faster, weekend commits have longer lifetimes, and race conditions are particularly hard to find; it also maps the corporate and independent contributions and outlines concrete process improvements that could cut bug lifetimes by about a third.
