The following commit has been merged in the master branch: commit 0893b89b1bc3640609d572b99201228cd99ad80b Author: Sven Eckelmann <sven.eckelmann(a)gmx.de> Date: Sat Sep 18 11:11:40 2010 +0000 batman-adv: wait for call_rcu before unloading module synchronize_rcu respective synchronize_net only waits for the rcu grace period to elapse and we may fail to finish the calls which were made to call_rcu in that time. In result the module could be unloaded during the execution of the RCU callbacks. rcu_barrier[1] will now wait for all outstanding RCU callbacks to finish before continuing.
