Paul Dagnelie a370182fed Add SCSI_PASSTHROUGH to zvols to enable UNMAP support ... When exporting ZVOLs as SCSI LUNs, by default Windows will not issue them UNMAP commands. This reduces storage efficiency in many cases. We add the SCSI_PASSTHROUGH flag to the zvol's device queue, which lets the SCSI target logic know that it can handle SCSI commands.
