From 10d50e748d983ff1003e0cf556ea17fa8f32c382 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 11:45:08 +0800 Subject: [PATCH] net,rcu: convert call_rcu(ip_mc_socklist_reclaim) to kfree_rcu() The rcu callback ip_mc_socklist_reclaim() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(ip_mc_socklist_reclaim).
