No

This commit trigger a checkpatch error because the following function add two semicolon.

RTE_EXPORT_EXPERIMENTAL_SYMBOL(rte_node_mbuf_dynfield_register, 25.07);;


Because the RTE_EXPORT_XXX_SYMBOL(XXX) macro do nothing, and this macro are placed out side
of function, it will left one semicolon after pre-process. This is not strictly comply with
C stand syntax.

In the V2 I will adopt following:
1\ #define RTE_EXPORT_XXX_SYMBOL(XXX) extern int __dummy_unused__ , this definition is comply
   with C stand syntax.
2\ keep the gen-version-map.py un-touch, because some commit are in-process different branch.

Thanks.
