And another. I would also like to flag the exports themselves as
indicated in the patch below. Thoughts?

Thanx, Paul

What: call_rcu(), call_rcu_bh(), and synchronize_kernel() change from
EXPORT_SYMBOL() to EXPORT_SYMBOL_GPL().
When: January 9, 2006
Files: kernel/rcupdate.c
Why: There are no known environments supporting RCU from which
one could reasonably expect to port a non-GPL kernel module
or driver to Linux.
Who: Paul E. McKenney <paulmck@us.ibm.com>
