Also of note:
In the latest kernel release, the most active 30 developers authored only 30% of the changes, while two years ago, the top 20 developers did 80% of the changes, he said. Kroah-Hartman himself is now doing more code reviewing than coding. “That’s all I do, is read patches these days,” he said.
