      IB/iser: Do not reduce max_sectors · 434dda42
      Sergey Gorenko authored
      The iSER driver reduces max_sectors. For example, if you load the
      ib_iser module with max_sectors=1024, you will see that
      /sys/class/block/<bdev>/queue/max_hw_sectors_kb is 508. It is an
      incorrect value. The expected value is (max_sectors * sector_size) /
      1024 = 512.
      
      Reducing of max_sectors can cause performance degradation due to
      unnecessary splitting of IO requests.
      
      The number of pages per MR has been fixed here, so there is no longer
      any need to reduce max_sectors.
