7 * struct trace_entry ent;
9 * <type2> <item2>[<len>];
13 * The <type> <item> is created by the __field(type, item) macro or

15 * We simply do "type item;", and that will create the fields

22 * DECLARE_EVENT_CLASS can be used to add a generic function
23 * handlers for events. That is, if all events have the same
24 * parameters and just have distinct trace points.
25 * Each tracepoint can be defined with DEFINE_EVENT and that
26 * will map the DECLARE_EVENT_CLASS to the tracepoint.
28 * TRACE_EVENT is a one to one mapping between tracepoint and template.
