undefined symbols (how to export symobls)

[sashan]

Hi

I'm trying get kernel module B to find a function/symbol S defined in 
kernel module A. Currently whenever B trys to use S it fails with

link_elf: symbol <S> undefined

I've tried adding EXPORT_SYMS = S to the Makefile.

A is loaded.

I'm using 5.4-RELEASE.

Thanks for the help.
