| From | "Paul E. McKenney" <> | Subject | [PATCH RFC tip/core/rcu 11/41] mac80211: Convert call_rcu() to kfree_rcu() | Date | Wed, 1 Feb 2012 11:41:29 -0800 |
| |
From: "Paul E. McKenney" <paul.mckenney@linaro.org>
The call_rcu() in mesh_gate_del() invokes mesh_gate_node_reclaim(), which simply calls kfree(). So convert the call_rcu() to kfree_rcu(), allowing mesh_gate_node_reclaim() to be eliminated.
