Linus Torvalds just drew a hard line on AI in the Linux kernel, and it’s not where some idealists wanted it. Writing on the kernel mailing list this week, the Linux creator said he is “willing to absolutely put my foot down” in support of AI-assisted development, telling those who object to LLM-generated code that they can “do the open-source thing and fork it. Or just walk away.”
The flashpoint was a discussion about Sashiko, an “agentic Linux kernel code review system” that its maintainers claim can independently identify 53.6 percent of bugs that human coders later fix in subsequent commits. That’s a striking hit rate for an automated tool, but it comes with a catch: the system also generates false positives, which its creators estimate are “well within [the] 20% range.” For kernel maintainers already drowning in patch review, that’s a non-trivial volume of noise.
One contributor cited the Software Freedom Conservancy’s recent position that the open source community “should support, not just tolerate, those who outright reject LLM-gen-AI systems.” Torvalds’ response was characteristically blunt. He made it clear that while no one is forced to use these tools, he will “very loudly ignore people who try to argue against other people from using it.”
This isn’t just another Torvalds flame. It’s a defining moment for how one of the world’s most critical software projects navigates the AI era. The kernel has always been a pragmatist’s domain — if a tool catches real bugs before they ship, the philosophical objections of anti-AI absolutists carry limited weight. The real tension isn’t about principles. It’s about whether maintainers can stomach the signal-to-noise ratio as these systems mature. My bet: they’ll adapt, because a 53% bug catch rate is too useful to leave on the table.
