      scsi: don't set tagging state from scsi_adjust_queue_depth · c8b09f6f
      Christoph Hellwig 提交于
      Remove the tagged argument from scsi_adjust_queue_depth, and just let it
      handle the queue depth.  For most drivers those two are fairly separate,
      given that most modern drivers don't care about the SCSI "tagged" status
      of a command at all, and many old drivers allow queuing of multiple
      untagged commands in the driver.
      
      Instead we start out with the ->simple_tags flag set before calling
      ->slave_configure, which is how all drivers actually looking at
      ->simple_tags except for one worke anyway.  The one other case looks
      broken, but I've kept the behavior as-is for now.
      
      Except for that we only change ->simple_tags from the ->change_queue_type,
      and when rejecting a tag message in a single driver, so keeping this
      churn out of scsi_adjust_queue_depth is a clear win.
      
      Now that the usage of scsi_adjust_queue_depth is more obvious we can
      also remove all the trivial instances in ->slave_alloc or ->slave_configure
      that just set it to the cmd_per_lun default.
