  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.

 29 * we must include module.h here before we play with any of
 30 * the TRACE_EVENT() macros, otherwise the tracepoints included
 31 * by module.h may break the build.
