1 | /* |
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. | |
