We should never issue a command that does not adhere to the limits set by the device driver. Upon inspection I agree this is busted and it's my fault. DM does not have a request_queue when stacking and as a result we ended up with two entities tracking whether a device supports clustering or not. And as it turns out the queue flag and the queue limits are not always in agreement. I've coded up a proper fix for this and will post a patch shortly. I'm just running a bunch of tests to ensure we do the right thing... -- Martin K.
