Subject: [PATCH] sched: Use RCU variant of list traversal in for_each_leaf_rt_rq()
Date: Mon, 15 Dec 2008 11:56:48 +0530 [thread overview]
Message-ID: <20081215062648.GB4337@in.ibm.com> (raw)
sched: Use RCU variant of list traversal in for_each_leaf_rt_rq()
for_each_leaf_rt_rq() walks an RCU protected list (rq->leaf_rt_rq_list),
but doesn't use list_for_each_entry_rcu(). Fix this.
