From 473c22d759e73cbbe604f41105b497817cc2ee8e Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Fri, 26 Jun 2009 10:45:48 +0000 Subject: [PATCH] bridge: Use rcu_barrier() instead of syncronize_net() on unload. 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.
