Linux.com has published an
interview with Thomas Gleixner with a focus on the realtime preemption
work. “The approach to funding these kinds of projects reminds me of the Mikado Game, which is popular in Europe, where the first player who picks up the stick and disturbs the pile often is the one who loses.

That’s puzzling to me, especially as many companies build key products
depending on these technologies and seem to take the availability and
sustainability for granted up to the point where such a project fails, or
people stop working on it due to lack of funding. Such companies should
seriously consider supporting the funding of the Real-Time project.“
