I agree that extending the existing "isolated" partition in cpusets is a
more integrated approach. For v3, I will explore a new mode for the
cpuset.cpus.partition interface to support dynamic nohz_full/nocb transitions.

The CPU offline logic in the RCU reconfiguration will be streamlined,
relying on the state managed by the cpuset/hotplug core.

Affinity management for workqueues and domains will be removed from the
DHM patches, as these are indeed already addressed by the isolated
partition logic.
