[PATCH 02/10] bridge: Use rcu_barrier() instead of syncronize_net()on unload.

From: Jesper Dangaard Brouer
Date: Tue Jun 23 2009 - 11:04:56 EST

When unloading modules that uses call_rcu() callbacks, then we must
use rcu_barrier(). This module uses syncronize_net() which is not
enough to be sure that all callback has been completed.
