Randy,

We're just trying to weed out the devices that report garbage in this field. But of course none of the devices I tested with put 0 in there.

The patch does fix problems for devices that report a nonsensical value. But it is a regression that it now prints a warning for devices that don't report an optimal I/O size at all.
Sorry about that. Will fix tomorrow!
