Thank you for pointing this out. I agree that coordination is key to avoid fragmentation of the isolation logic in the kernel. In V13, I will focus on integrating this "Dynamic Housekeeping" logic directly with the cpuset subsystem. The idea is to allow the root cpuset to act as the orchestrator for both task isolation (which it already handles) and kernel overhead isolation (which DHEI enables). > Also, Waiman Long should definitely be in the CC list for this. Acknowledge. I will make sure to CC Waiman and the cgroups mailing list in the next iteration.
