Let me explain the purpose of this patch. The patch was created to remove the requirement to restart the X server after a kernel evdev input device has changed its axis parameters.
You will only see this patch in action if you: 1: Create a calibration utility. 2: Then send ioctl's to the device with new axis parameters The X server will then read these new settings (without the need for restart) and the mouse / pointer will behave appropriately.
