It was the case earlier. But Ed changed it (to send a mode select only when needed) before I moved the emc code to be under SCSI Hardware Handler. Later Hannes made it still better. IOW, The EMC code in SCSI hardware handler is smart to find out if the trespass/mode_select command need to be sent down the wire (they first do a inquiry and if the state is "OWNED", they just return). Hannes, MikeC, correct me if I am wrong. > > Alasdair -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
