1 | /* |
2 | * Stage 1 of the trace events. | |
3 | * | |
4 | * Override the macros in <trace/trace_events.h> to include the following: | |
5 | * | |
6 | * struct ftrace_raw_<call> { | |
7 | * struct trace_entry ent; | |
8 | * <type> <item>; | |
9 | * <type2> <item2>[<len>]; | |
10 | * [...] | |
11 | * }; | |
12 | * | |
13 | * The <type> <item> is created by the __field(type, item) macro or | |
14 | * the __array(type2, item2, len) macro. | |
15 | * We simply do "type item;", and that will create the fields | |
16 | * in the structure. | |
