Each trace point used by this\nwill share most of the code, and bring down the size of the kernel\nwhen there are several duplicate events.\n\nUsage is:\n\nTRACE_EVENT_TEMPLATE(name, proto, args, tstruct, assign, print);\n\nWhich would be the same as defining a normal TRACE_EVENT.\n\nTo create the trace events that the trace points will use:\n\nDEFINE_EVENT(template, name, proto, args) is done. The template\nis the name of the TRACE_EVENT_TEMPLATE to use. The name is the\nname of the trace point. The parameters proto and args must be the same\nas the proto and args of the template.
