/*

* Stage 1 of the trace events.
|
|
*
|
|
* Override the macros in <trace/trace_event_types.h> to include the following:
|
|
*
|
|
* struct ftrace_raw_<call> {
|
|
* struct trace_entry ent;
|
|
* <type> <item>;
|
|
* [...]
|
|
* };
|
|
*
|
|
* The <type> <item> is created by the TRACE_FIELD(type, item, assign)
|
|
* macro. We simply do "type item;", and that will create the fields
|
|
* in the structure.
