Have you been using this and are referencing this because it is useful or did you just happen to find it? People have been complaining about this and I *think* it fails to work in multi-CPU scenarios (it might work if the task is restricted to single CPU usage). Not entirely certain. But complains, that I am certain of. There is replacement underway to utilize SCHED_DL for this as in "Hierarchical Constant Bandwidth Server (HCBS)" https://lore.kernel.org/all/20260430213835.62217-1-yurand2000@gmail.com/
