add_kallsyms() assigns the RCU pointer module::kallsyms and setups the structures behind it which point to init-data. The module was not published yet, nothing can see the kallsyms pointer and the data behind it. Also module's init function was not yet invoked. There is no need to use rcu_dereference() here, it is just to keep checkers quiet. The whole RCU read section is also not needed. Use a local kallsyms pointer and setup the data structures. Assign that pointer to the data structure at the end via rcu_assign_pointer().
