Hi, In v6.10 kernel, some tracepoints events are added to record IEEE 1394 asynchronous communication. In the case that multiple 1394 OHCI controllers are available in Linux system, it is hard to distinguish the controller used for the communication, since these events have no member in their data structure to express the used controller. It is a bit inconvenient to diagnose things. This series of patches is an attempt to solve the issue. In Linux FireWire core, the available controllers are maintained in list, and each of them has its own numeric identifier (=card_index). In this series, the index value is added to the data structure. I would like to put the change to v6.10-rc4 (or later) as the part of fixes if receiving no objections.
