* Trace files that want to automate creation 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. |
