| 3 | * Trace files that want to automate creation of all tracepoints defined
|
| 4 | * in their file should include this file. The following are macros that the
|
| 5 | * trace file may define:
|
| 6 | *
|
| 7 | * TRACE_SYSTEM defines the system the tracepoint is for
|
| 8 | *
|
| 9 | * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h
|
| 10 | * This macro may be defined to tell define_trace.h what file to include.
|
| 11 | * Note, leave off the ".h".
|
| 12 | *
|
| 13 | * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace
|
| 14 | * then this macro can define the path to use. Note, the path is relative to
|
| 15 | * define_trace.h, not the file including it. Full path names for out of tree
|
| 16 | * modules must be used.
