ext3: Flush disk caches on fsync when needed
[deliverable/linux.git] / include / trace / ftrace.h
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.
