      writeback: account IO throttling wait as iowait · d25105e8
      Wu Fengguang authored
      
      
      It makes sense to do IOWAIT when someone is blocked
      due to IO throttle, as suggested by Kame and Peter.
      
      There is an old comment for not doing IOWAIT on throttle,
      however it has been mismatching the code for a long time.
      
      If we stop accounting IOWAIT for 2.6.32, it could be an
      undesirable behavior change. So restore the io_schedule.

      elv_iosched_store(): fix strstrip() misuse · 8c279598
      KOSAKI Motohiro authored
      
      
      elv_iosched_store() ignore the return value of strstrip().  It makes small
      inconsistent behavior.
      
      This patch fixes it.
