How did you add the other cpu? to the "all" cpuset? I don't think I am
percolating the changes to "cpus" field of parent to child cpuset, which
may explain why tasks continue to run on cpu0. Achieving this change
atomically for all child cpusets again is something I don't know whether
cpuset code can handle well.
