From d4ee9aa33db94120532601a22566e989efc3e70c Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 12:11:44 +0800 Subject: [PATCH] ipc,rcu: Convert call_rcu(ipc_immediate_free) to kfree_rcu() The rcu callback ipc_immediate_free() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(ipc_immediate_free).
