    tracing: Remove mock up poll wait function · b1169cc6
    Steven Rostedt (Red Hat) authored
    Now that the ring buffer has a built in way to wake up readers
    when there's data, using irq_work such that it is safe to do it
    in any context. But it was still using the old "poor man's"
    wait polling that checks every 1/10 of a second to see if it
    should wake up a waiter. This makes the latency for a wake up
    excruciatingly long. No need to do that anymore.
    
    Completely remove the different wait_poll types from the tracers
    and have them all use the default one now.
