Hi, IEEE 1394 bus is under bus-reset state when the physical state of bus is changed; e.g. bus topology change by adding new nodes in the bus. It is important to handle the state appropriately for the maintenance of bus. This series of change adds some tracepoints events to trace the events related to bus-reset. Some kernel log messages are obsoleted and deleted. It also includes for 1394 OHCI driver so that bus-reset IRQ event is recorded as much as possible, and obsoletes bus-resets bit from debug parameter successfully.
