      [SCSI] Silencing 'killing requests for dead queue' · 74571813
      Hannes Reinecke authored
      When we tear down a device we try to flush all outstanding
      commands in scsi_free_queue(). However the check in
      scsi_request_fn() is imperfect as it only signals that
      we _might start_ aborting commands, not that we've actually
      aborted some.
      So move the printk inside the scsi_kill_request function,
      this will also give us a hint about which commands are aborted.

          [SCSI] Fix block queue and elevator memory leak in scsi_alloc_sdev
      
      Doesn't completely do the teardown.  The true fix is to do a proper
      teardown instead of hand rolling it

      .. with new name.  Because nothing says "really solid kernel release"
      like naming it after an extinct animal that just happened to be in the
      news lately.
