[PATCH 07/10] decnet: Use rcu_barrier() on module unload. From: Jesper Dangaard Brouer <hawk@xxxxxxx> The decnet module unloading as been disabled with a '#if 0' statement, because it have had issues. We add a rcu_barrier() anyhow for correctness. The maintainer (Chrissie Caulfield) will look into the unload issue when time permits.
