From: John Harrison <John.C.Harrison@xxxxxxxxx>
All the code above is now using requests not seqnos so it is possible to convert
the trace functions across. Note that rather than get into problematic reference
counting issues, the trace code only saves the seqno and ring values from the
request structure not the structure pointer itself.
For: VIZ-4377
