I agree, it has to be a config/makefile issue. Well, i got past the problem of nothing being exported. My problem was the absence of #include module.h at the top of my file. Now i have another problem with the symbol being exported. With module versioning turned on, the symbol isn't being hashed correctly. grep foo /proc/ksyms reports foo_R__ver_foo What's going on here?
