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. -- Regards, vatsa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
