tracing: Undef TRACE_EVENT_FN between trace events headers inclusion
The recent commit: tracing/events: fix the include file dependencies fixed a file dependency problem while including more than one trace event header file. This fix undefined TRACE_EVENT after an event header macro preprocessing in order to make tracepoint.h able to correctly declare the tracepoints necessary for the next event header file. But now we also need to undefine TRACE_EVENT_FN at the end of an event header file preprocessing for the same reason. This fixes the following build error: In file included from include/trace/events/napi.h:5, from net/core/net-traces.c:28: include/linux/tracepoint.h:285:1: warning: "TRACE_EVENT_FN" redefined In file included from include/trace/define_trace.h:61, from include/trace/events/skb.h:40, from net/core/net-traces.c:27: include/trace/ftrace.h:50:1: warning: this is the location of the previous definition In file included from include/trace/events/napi.h:5, from net/core/net-traces.c:28: include/linux/tracepoint.h:285:1: warning: "TRACE_EVENT_FN" redefined In file included from include/trace/define_trace.h:61, from include/trace/events/skb.h:40, from net/core/net-traces.c:27: include/trace/ftrace.h:50:1: warning: this is the location of the previous definition Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Masami Hiramatsu <mhiramat@redhat.com> Cc: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Li Zefan <lizf@cn.fujitsu.com> LKML-Reference: <20090827161732.GA7618@nowhere> Signed-off-by: Ingo Molnar <mingo@elte.hu>
