    Not sure what you are talking about. These "random delays" are not for
    the interface, but instead to force some events to happen and to make
    sure they did.

    As the subject states, this is for "ftracetest" which is the selftests
    for ftrace.

    The usleep is basically a "do something to trigger events", and we
    don't want to wait long in doing it.
