    Subject[patch v3 0/3] percpu_counter: cleanup and fix
    Cleanup percpu_counter code and fix some bugs. The main purpose is to convert
    percpu_counter to use atomic64, which is useful for workloads which cause
    percpu_counter->lock contented. In a workload I tested, the atomic method is
    7x faster (please see patch 3 for detail).

    Note, patch 3 is against Christoph's 'percpu: preemptless __per_cpu_counter_add'
