--- Comment #2 from Josh Stone <jistone at redhat dot com> ---
In Fedora, I only see the module_* tracepoints without any "system:" prefix.
include/trace/events/module.h has:

  #ifdef CREATE_TRACE_POINTS
  #undef TRACE_SYSTEM
  #define TRACE_SYSTEM module
  #endif

AFAICS we don't set CREATE_TRACE_POINTS.  I'm not sure, but maybe we should.

FWIW sched.h and writeback.h also use CREATE_TRACE_POINTS, but only to guard
some helper functions, not to guard TRACE_SYSTEM.  I think that will harmless
to tracequery if those functions are added, as long as they do compile ok.
