Keynote: Kernel Developer Roundtable
summary
Rust adoption moves forward but slowly: tooling and buildbot friction delays conversions (one btrfs proof‑of‑concept stalls until build/test support matures), while a real example shows a Rust binder driver runs on a phone. Deep subsystems produce surprising cleanup: VFS lifetime work yields a 75‑page VFS lifetime doc; core timers get extensive refactoring with Rust patches appearing. Hardware trends push work on CXL/persistent memory and confidential computing, documentation and regression tracking remain underfunded despite ~200 new kernel developers per release.
