OpenBSD ext4fs sparks AI copyright fight

Technically, this is a credible first pass; socially, it is a warning shot. Kernel work can absorb AI assistance, but OpenBSD's bar shows that provenance and maintainability still outrank velocity.

• –The driver reportedly exists to ease the pain of multi-terabyte disks and long `fsck` runs on OpenBSD.
• –Missing journaling means the current branch is still short of the durability story that motivated the work.
• –OpenBSD reviewers are likely to care more about who can vouch for the code's lineage than whether the demo boots.
• –Even a clean-room claim does not remove the harder problem: LLM-shaped code is expensive to audit, maintain, and defend later.
• –If this goes anywhere, the short-term win is compatibility with ext4-formatted Linux media, not a wholesale filesystem swap.
