On September 19, Thomas Gleixner delivered the pull request for the
realtime preemption enablement patches to Linus Torvalds — in printed form,
wrapped in gold, with a ribbon, as Torvalds had requested. It was a
significant milestone, marking the completion of a project that required
20 years of effort. Congratulations are due to everybody involved.

Torvalds acted on
the pull request the following morning.
