I did look at them briefly back then, but, probably, too briefly. One of the settings - enable_clustering - seems to be pretty critical and can only be verified to be safe by intensive testing of various chips / cards. So, how about making it a run-time parameter? A module parameter is the easiest, but then each lld would have to do the same thing more or less. A sysfs attribute - but where? It is a queue attribute, but st/sg don't expose their queues in /sys... Maybe under /sys/class/scsi_host? Similar for max_sectors?
