If a function is truly inlined, what address is used to be exported?

(Though gcc stops you from that idiocy - if you take the address of the
function, gcc will emit a non-inlined version whether you like it or
not.  Of course, external references to that function will involve
a function call and not be inlined.)

Most of the kernel sticks a 'static inline' in a .h file that's included
in every .c that needs it, and doesn't bother with the EXPORT_SYMBOL.
