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