    [PATCH] Update cfq io scheduler to time sliced design · 22e2c507
    Jens Axboe authored
    This updates the CFQ io scheduler to the new time sliced design (cfq
    v3).  It provides full process fairness, while giving excellent
    aggregate system throughput even for many competing processes.  It
    supports io priorities, either inherited from the cpu nice value or set
    directly with the ioprio_get/set syscalls.  The latter closely mimic
    set/getpriority.
    
    This import is based on my latest from -mm.
