Currently, the napi's tracepoint works will is depend on
"DECLARE_TRACE" definiens in include/trace/define_trace.h,
like below:

#include <trace/events/skb.h>    // include define_trace.h
#include <trace/events/napi.h>

there have error, if we remove "#include <trace/events/skb.h>"
or include napi.h in the front of include skb.h, It should
depend on the definiens in include/linux/tracepoint.h and we
can remove the "DECLARE_TRACE" definiens in
include/trace/define_trace.h, because "TRACE_EVENT" not use it

This will collide with tracing bits in the networking tree. The 
skb-tracing plugin there should be turned into proper TRACE_EVENT() 
tracepoints.

Neil was away for some time but i think soon we should see some 
movement here.

Thank you Ingo, yes, I'm back from the beach now and will look at this shortly.
I concur, we should just convert the napi_poll tracepoint to be defined via the
TRACE_EVENT macro, same as the kfree_skb tracepoint.  Xaio would you like to
take care of that, or shall I?

Best
