This patchset documents these differences. This is related to the previous patchset titled "cgroup, docs: Clarify interaction of RT processes with cgroup v2 cpu controller" (https://lore.kernel.org/all/20250305-rt-and-cpu-controller-doc-v1-0-7b6a6f5ff43d@sony.com/), which focused solely on RT processes. The current patchset incorporates the previous feedback and expands on the scope of scheduling policies.
