It's hard to tell whether you're justifying having the EXPORT_SYMBOLs
there or not from your reply.
Just because you add them as declarations to a header file does not mean
you have to add EXPORT_SYMBOLs for them. The only thing that this macro
does is make them available to modules.
In any case, if functions are marked as __init (or similar, which some
are) then they must not be exported - they won't exist when modules are
available to be loaded. Instead, their symbols will point to some
random data which has replaced the code.
