From 88b4a0347a81539884df5ad535e10cf9fa87d8d4 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 12:15:02 +0800 Subject: [PATCH] net,rcu: convert call_rcu(xt_osf_finger_free_rcu) to kfree_rcu() The rcu callback xt_osf_finger_free_rcu() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(xt_osf_finger_free_rcu).
