    Subject[PATCH 08/39] autonuma: mm_autonuma and sched_autonuma data structures
    Date
    Define the two data structures that collect the per-process (in the
    mm) and per-thread (in the task_struct) statistical information that
    are the input of the CPU follow memory algorithms in the NUMA
    scheduler.
