[PATCH 15/36] net,rcu: convert call_rcu(ipv6_mc_socklist_reclaim) to kfree_rcu()
From: Lai Jiangshan <hidden>
Date: 2011-03-18 03:59:08
The rcu callback ipv6_mc_socklist_reclaim() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(ipv6_mc_socklist_reclaim). Signed-off-by: Lai Jiangshan <redacted> --- net/ipv6/mcast.c | 8 ++------ 1 files changed, 2 insertions(+), 6 deletions(-)
