- Due to resource allocation issues in the Linux SCSI mid-layer, using
- a high number of commands per device may result in memory allocation
- failures when many devices are attached to the system. For this reason,
- the default is set to 32. Higher values may result in higher performance
- on some devices. The upper bound is 253. 0 disables tagged queueing.
