From 06a9701f4b3e3381dea96fee1cc8a3bb41b0a1f1 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 1 Dec 2010 01:37:42 +0000 Subject: [PATCH] __in_dev_get_rtnl() can use rtnl_dereference() If caller holds RTNL, we dont need a memory barrier (smp_read_barrier_depends) included in rcu_dereference(). Just use rtnl_dereference() to properly document the assertions. Signed-off-by: Eric Dumazet Signed-off-by: David S.
