I'm working on a partitioned EDF scheduler right now, and I have to
face several issues, starting from the interface to use to expose the
EDF scheduler to userspace, and the integration with the existing
sched_rt policy.

By now I'm experimenting with an additional sched_class that implements
a SCHED_EDF policy, extending the POSIX struct sched_param with the
EDF parameters of the task, do you see any better way to do that?
Could that approach be reasonable?

Michael
