While testing the WRITE SCATTERED command support in a new sg3_utils utility (sg_write_x) it was helpful to have a target that supported this command. This command might be attractive to other kernel subsystems. Even if end devices don't support this command yet, it would most likely be a performance win if SCSI LLDs supported it (by breaking it down to a series of WRITE commands), as that would cut down the overhead of the block layer, the ULD (e.g. sd) and the SCSI midlevel.
