This too is only cosmetic and doesn't affect the code at all, because a TRACE_EVENT() is really just: #define TRACE_EVENT(name, proto, args, tstruct, assign, print) \ DECLARE_EVENT_CLASS(name, \ PARAMS(proto), \ PARAMS(args), \ PARAMS(tstruct), \ PARAMS(assign), \ PARAMS(print)); \ DEFINE_EVENT(name, name, PARAMS(proto), PARAMS(args)); -- Steve > > It's pretty clear from the prototype that it expects a "ret" argument, > so I don't see the need to also state it in the template name. > >
