From: John Harrison <John.C.Harrison@xxxxxxxxx>
Added the request structure's 'uniq' identifier to the trace information. Also
renamed the '_complete' trace event to '_notify' as it actually happens in the
IRQ 'notify_ring()' function. Additionally there is now a new '_complete' trace
event which occurs when a request structure is marked as complete.
v2: New patch added to series.
For: VIZ-4377
