Thomas de Grivel submitted an ext4 filesystem implementation to OpenBSD using ChatGPT and Claude Code — without reading any Linux source files — sparking debate about LLM-generated code in open source projects. The driver passes e2fsck and supports full read/write but lacks journaling; its AI provenance raised both technical credibility and copyright concerns in the OpenBSD community. The episode adds to a broader pattern of LLM-driven reimplementation being used to sidestep copyleft restrictions, following a similar controversy with the Python chardet module.
