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. The intention is to add a new '_complete' trace
event which occurs when a request structure is actually marked as complete.
However, at the moment the completion status is re-tested every time the query
is made so there isn't a completion event as such.
v2: New patch added to series.
v3: Rebased to remove completion caching as that is apparently contentious.
