The integration of AI coding agents into software development and reverse engineering has seen significant activity. The open-source REA (Reverse Engineer Anything) toolkit has gained substantial popularity, acting as a bridge between AI agents like Claude Code, Cursor, and Codex and traditional reverse-engineering tools such as Ghidra and IDA Pro. This allows AI to analyze software through natural language without source code access.

Concurrently, Linux creator Linus Torvalds has utilized Anthropic’s Claude Code to assist in kernel development. Recent work focused on improving page-cache read performance by addressing a bottleneck related to folio reference-count contention. Under Torvalds’ supervision, the AI assisted in writing implementation code, test programs, review material, and initial technical documentation.

In testing on an Intel laptop, the proposed changes—which utilize the Linux Read-Copy-Update (RCU) mechanism to allow a lockless read path—showed a significant throughput increase for 16-byte reads, rising from approximately 9–10 million to 30–33 million per second. However, the development remains experimental; reviewers have identified a race condition and raised concerns regarding memory reclamation. Torvalds has since transitioned the further development of these patches to kernel developer Kiryl Shutsemau.

## Claims

- Linus Torvalds used Anthropic’s Claude Code to write Linux kernel patches, test programs, and technical documentation under his direction. (corroborated by 3 sources)
- The patches aim to address a performance bottleneck in the page-cache read path by reducing folio reference-count updates. (corroborated by 3 sources)
- The proposed approach uses the Read-Copy-Update (RCU) mechanism to delay reusing page-cache memory until an RCU grace period ends. (corroborated by 2 sources)
- Benchmarks on an Intel laptop showed a throughput increase from approximately 9-10 million to 30-33 million 16-byte reads per second. (single source)
