Linus Torvalds Puts His Name on a Claude Code Kernel Patch for the First Time; Eight-Thread Cache Read Throughput Triples
Linus Torvalds submitted a Linux kernel patch series whose cover letter states that an LLM coding assistant (Claude Code) produced the code, tests, list review, and initial draft under his guidance, yielding a threefold increase in eight-thread 16-byte cache read throughput. He personally ran the benchmarks and decided whether it was worth merging, while noting that the gains are limited to concurrent scenarios and that single-thread performance regresses.
