/*
|
|
* 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.
