Existing drivers all work properly because the reference counting of urbs is already present, why add duplicate counters? That actually leads to bugs. I don't see the need for this code, please explain it better if you wish for it to be accepted. What has it found/fixed that we have not found yet? What does it allow you to do that you can't do today with the existing code? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
