If you read the page, it simply states that you can tweak the parameters of the existing scheduler, not replace it entirely.

- noughth 9y agoThe scheduling policies listed on the man page I linked share some generic kernel code, but I wouldn't classify them as the same scheduler. If you look inside the kernel/sched/ directory in the source, you'll find that an instance of `struct sched_class` is defined for each scheduler class. There are dl_sched_class, rt_sched_class, fair_sched_class, and idle_sched_class. You can see in `pick_next_task` in core.c that these class structs are iterated over, calling into each scheduler's own `pick_next_task`: http://elixir.free-electrons.com/linux/v4.13.9/source/kernel/sched/core.c#L3207 http://elixir.free-electrons.com/linux/v4.13.9/source/kernel...
