What is it about?
This paper describes the SCHED_DEADLINE scheduling policy provided by the mainline Linux kernel, which implements the CBS algorithm described in "Integrating multimedia applications in hard real-time systems" (my first research paper, from 1998). The SCHED_DEADLINE implementation is described and evaluated through a set of experiments.

Why is it important?
This is an example of technology transfer from a research paper to a real OS kernel used by many people all over the world. It shows how real-time research can improve the performance of software projects.
Perspectives
Although I was not directly involved in the SCHED_DEADLINE development, I am the author of the scheduling algorithm implemented by this policy. It is great to see your research work implemented in a real software used by many people!
