From fc766e4c4965915ab52a1d1fa3c7a7b3e7bc07f0 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 29 Oct 2010 03:09:24 +0000 Subject: decnet: RCU conversion and get rid of dev_base_lock While tracking dev_base_lock users, I found decnet used it in dnet_select_source(), but for a wrong purpose: Writers only hold RTNL, not dev_base_lock, so readers must use RCU if they cannot use RTNL. Adds an rcu_head in struct dn_ifaddr and handle proper RCU management. Adds __rcu annotation in dn_route as well. Signed-off-by: Eric Dumazet Acked-by: Steven Whitehouse Signed-off-by: David S.
