    There's not that many that are in perf_event.h and are only used in
    kernel/event/core.c.

    Below is a generated list of all exported functions and their usage sites. Out
    of 40 functions 7 should not be exported:

    __perf_sw_event()
    perf_swevent_put_recursion_context()
    perf_pmu_unregister()
    perf_output_copy()
    __perf_event_task_sched_in()
    __perf_event_task_sched_out()
    perf_event_read_value()

    Thanks,

    Ingo
