As with one of your other patches, please don't change the defaults and hide them under a module parameter. If you're adding a module parameter, leave the default behavior alone. This also seems like something that might be nicer as a user-space knob in generic form (similar to "/sys/class/devcoredump/disabled", except on a per-device basis, and fed back to the driver so it doesn't waste time generating such dumps), but I suppose I can see why a module parameter (so you can just stick your configuration in /etc/modprobe.d/) might be easier to deal with in some cases.
