      [SCSI] seperate max_sectors from max_hw_sectors · defd94b7
      Mike Christie 提交于
      - export __blk_put_request and blk_execute_rq_nowait
      needed for async REQ_BLOCK_PC requests
      - seperate max_hw_sectors and max_sectors for block/scsi_ioctl.c and
      SG_IO bio.c helpers per Jens's last comments. Since block/scsi_ioctl.c SG_IO was
      already testing against max_sectors and SCSI-ml was setting max_sectors and
      max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only
      prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set
      a valid max_hw_sectors for all LLDs. Today if a LLD does not set it
      SCSI-ml sets it to a safe default and some LLDs set it to a artificial low
      value to overcome memory and feedback issues.
      
      Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024,
      drivers that used to call blk_queue_max_sectors with a large value of
      max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.
