From eaa184a1a1cda3991420c47bc960ddea6cbacff2 Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Mon, 8 Jun 2009 03:11:43 +0000 Subject: sctp: protocol.c call rcu_barrier() on unload. On module unload call rcu_barrier(), this is needed as synchronize_rcu() is not strong enough. The kmem_cache_destroy() does invoke synchronize_rcu() but it does not provide same protection.
