Subject: [PATCH 33/36] vmalloc,rcu: convert call_rcu(rcu_free_va) to kfree_rcu()
Date: Fri, 18 Mar 2011 12:12:19 +0800 [thread overview]
Message-ID: <4D82DBA3.5020306@cn.fujitsu.com> (raw)
The rcu callback rcu_free_va() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(rcu_free_va).
