If an unloadable module uses RCU callbacks, it need to use rcu_barrier() so that the module may be safely unloaded. While hacking on a netfilter module of my own, I learned the importance of calling rcu_barrier() instead of only a synchronize_rcu() on module unload (iif using any call_rcu() callbacks). synchronize_rcu() does wait for a grace period to elapse, but it does not wait for the callbacks to complete. ... I have made a patch for each individual module, so objections can be made on a per module basis. I have Cc'ed all of the patches to the maintainers of each module (according to the MAINTAINERS file).
Acked-by: Patrick McHardy <kaber@xxxxxxxxx> for patches 1 and 2, good catch. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
