From 37b6b935e96e837ccc60812c03e9f92e7dce2e61 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Tue, 15 Mar 2011 18:01:42 +0800 Subject: [PATCH] net,rcu: convert call_rcu(listeners_free_rcu) to kfree_rcu() The rcu callback listeners_free_rcu() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(listeners_free_rcu).
