  log: |
    Enhance disk metrics by calculating a weighted sum that is incremented
    by the number of concurrent I/O requests. Also introduce a new disk_wait()
    function to measure requests waiting in a bufq.
    iostat -y now reports data about waiting and active requests.

    So far only drivers using dksubr and dk, ccd, wd and xbd collect data about
    waiting requests.
