These are not trace functions, but trace point objects, I see this is
common usage in other libraries too, but can you please explain why we
need to export the trace point objects from the .so file?

For some datapath functions, which are static inline functions, trace
point objects are need to be accessible by application, it is OK to
export them, but they are very limited, but I am not clear why exporting
all of them is required.
