Szmigiero" And rename existing load_device_config_state trace event to load_device_config_state_end for consistency since it is triggered at the end of loading of the VFIO device config state. This way both the start and end points of particular device config loading operation (a long, BQL-serialized operation) are known. Signed-off-by: Maciej S.
