Documenting the Design of the Linux Kernel

on YouTube ↗53m

" summary

Proposes a machine‑readable requirement template that embeds stable ID/hash key comments in kernel source, auto-generates SPDX‑style IDs, and links each low‑level requirement to pass/fail tests and code‑coverage. Pilots on the tracing subsystem produce RFC kernel‑doc headers, an automation script, and a real fix (ftrace event enabled/disabled) that lands upstream and in LTS. Roadmap includes kernel CI linkage to map requirements→tests and tooling to alert when hashes diverge.
