Isn't the deadline realtime scheduler optional? How many distros do actually ship it in their default kernels? I honestly didn't manage to keep track of this.

The deadline scheduler is upstream, see "man 7 sched" for a description: https://man7.org/linux/man-pages/man7/sched.7.html

What is not upstream (yet) is the PREEMPT_RT patch which makes all kernel threads fully preemptible.
