| 10 | * Trace files that want to automate creationg of all tracepoints defined | |
| 11 | * in their file should include this file. The following are macros that the | |
| 12 | * trace file may define: | |
| 13 | * | |
| 14 | * TRACE_SYSTEM defines the system the tracepoint is for | |
| 15 | * | |
| 16 | * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h | |
| 17 | * This macro may be defined to tell define_trace.h what file to include. | |
| 18 | * Note, leave off the ".h". | |
| 19 | * | |
| 20 | * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace | |
| 21 | * then this macro can define the path to use. Note, the path is relative to | |
| 22 | * define_trace.h, not the file including it. Full path names for out of tree | |
| 23 | * modules must be used. | |
