Background & analysis
On October 12, 2026, cnBeta reported that Linus Torvalds, the creator of the Linux kernel, is working on a Linux kernel performance optimization with the help of Claude Code, an AI coding tool. The work targets a bottleneck in the kernel's memory management: when multiple threads read the same file at the same time, contention arises from reference counting on memory pages. The stated goal is to cut down that contention and improve file read efficiency.
According to the report, Torvalds is not only using Claude Code to help write code, but also relying on it to write test programs, carry out code review, and draft the accompanying patch description.
The public information stops there. The report does not specify how the optimization is implemented, which kernel version it concerns, what performance gains were measured, or whether the patch has been submitted or merged.

开源中国AI score 70According to cnBeta, Linux founder Linus Torvalds recently used LLMs such as Claude Code to analyze and refactor complex kernel code. While improving code readability, he not only confirmed a previously reported defect but also unexpectedly uncovered three decade-old vulnerabilities related to the Linux kernel's associative array implementation.
cnBetaAI score 65Linux creator Linus Torvalds is using Claude Code on a kernel memory-management optimization that aims to cut contention over page reference counts when multiple threads read the same file, improving file-read throughput. According to cnBeta, he also relies on the tool to write test programs, review code and draft patch descriptions.
