   2  * Stage 1 of the trace events.
   3  *
   4  * Override the macros in <trace/trace_event_types.h> to include the following:
   5  *
   6  * struct ftrace_raw_<call> {
   7  *      struct trace_entry              ent;
   8  *      <type>                          <item>;
   9  *      [...]
  10  * };
  11  *
  12  * The <type> <item> is created by the TRACE_FIELD(type, item, assign)
  13  * macro. We simply do "type item;", and that will create the fields
  14  * in the structure.
