| 2 | * Trace files that want to automate creationg of all tracepoints defined |
| 3 | * in their file should include this file. The following are macros that the |
| 4 | * trace file may define: |
| 5 | * |
| 6 | * TRACE_SYSTEM defines the system the tracepoint is for |
| 7 | * |
| 8 | * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h |
| 9 | * This macro may be defined to tell define_trace.h what file to include. |
| 10 | * Note, leave off the ".h". |
| 11 | * |
| 12 | * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace |
| 13 | * then this macro can define the path to use. Note, the path is relative to |
| 14 | * define_trace.h, not the file including it. Full path names for out of tree |
| 15 | * modules must be used. |
