Subject: Kernel module unable to find an exported symbol

Hi everyone, I have two kernel modules I am developing, both use the
call_rcu exported function. The core module finds it no problem,
installs, and uses it.  The second module however when I try to insmod
it complains:

Unknown symbol call_rcu

I have verified that it is exported via /proc/kallsyms:
c04348c8 T call_rcu

I am at a loss as to how to proceed, can anyone shed some light on how
this could be happening? Or how to diagnose and debug the problem?

Thanks,
David

ps please CC me on a reply, thank you!
