No, you want EXPORT_SYMBOL(function_1) here.

And just another function pointer assignment here

The correct way to do this would be just use a call through a function
pointer - that way any other code that's at a different point in
execution doesn't end up calling something unexpected.(because let's
face it - if the code is expecting to call function_1, and it suddenly
ends up in function_2 anyhow, it will quite possibly misbehave).
