      [BLOCK] Fix bounce limit address check · 8269730b
      Andi Kleen authored
      Do a safer check for when to enable DMA. Currently we enable ISA DMA
      for cases that do not need it, resulting in OOM conditions when ZONE_DMA
      runs out of space.

      [PATCH] cfq-iosched: many performance fixes · caaa5f9f
      Jens Axboe authored
      This is a collection of patches that greatly improve CFQ performance
      in some circumstances.
      
      - Change the idling logic to only kick in after a request is done and we
        are deciding what to do. Before the idling included the request service
        time, so it was hard to adjust. Now it's true think/idle time.
      
      - Take advantage of TCQ/NCQ/queueing for seeky sync workloads, but keep
        it in control for sync and sequential (or close to) workloads.
      
      - Expire queues immediately and move on to other busy queues, if we are
        not going to idle after the current one finishes.
      
      - Don't rearm idle timer if there are no busy queues. Just leave the
        system idle.

      [PATCH] cfq-iosched: correctly set ioprio on both targets · 35e6077c
      Jens Axboe authored
      Patch originally from Vasily Tarasov <vtaras@sw.ru>
      
      If you set io-priority of process 1 using sys_ioprio_set system call by
      another process 2 (like ionice do), then cfq_init_prio_data() function
      sets priority of process 2 (current) on queue of process 1 and clears
      the flag, that designates change of ioprio.  So the process  1 will work
      like with priority of process 2.
      
      I propose not to call cfq_init_prio_data() on io-priority change, but
      only mark queue as queue with changed prority.  Every time when new
      request comes cfq-scheduler checks for this flag and atomaticaly changes
      priority of queue to new value.
