Currently, sym_add_exported() does not allocate a symbol if the same name symbol already exists in the hash table. This does not reflect the real use cases. You can let an external module override the in-tree one. In this case, the external module will export the same name symbols as the in-tree one. However, modpost simply ignores those symbols, then Module.symvers for the external module loses its symbols. sym_add_exported() should allocate a new symbol.
