    Subject[PATCH 16/39] autonuma: call autonuma_setup_new_exec()
    Date
    This resets all per-thread and per-process statistics across exec
    syscalls or after kernel threads detached from the mm. The past
    statistical NUMA information is unlikely to be relevant for the future
    in these cases.
