For some transports, not only the channel but also the Scsi_Host is meaningless. Such transports deal only with targets and logical units. This includes all multi-protocol + multi-bus or network infrastructures such as iSCSI, USB, IEEE 1394. -- Stefan Richter -=====-=-==- --== --=== http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
