2 * Trace files that want to automate creation 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.
