This seems like it might be information that other adapters could, in theory, also provide. Maybe the first set of stats should be added to /sys/class/scsi_host/hostN/ and the second set to /sys/class/scsi_device/H:C:T:L/ ? The names of the individual files make sense to me. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step."
