The change is in my version so I won't forget about it. You can assess it if you want. Note that it is just a quick (but probably correct) fix for "not mature" support for larger I/O clusters. The problem could also be fixed by initializing d_maxio to nonzero in devswitches for all disk devices. Then the < 0 case would only occur for disk devices that you forgot.
