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.
