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.
>> Does it really belong in an LTS kernel?
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!
