McKenney" , Ingo Molnar , Andrew Morton Subject: [PATCH 0/2] rcu/ftrace: Add rcu_dereference_raw_notrace() and friends Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Paul, As you suggesed using the name "*_notrace", I updated my patch. There's two patches now. The first patch adds two new APIs to the RCU system. rcu_dereference_raw_notrace() hlist_for_each_entry_rcu_notrace() I needed the second one as the function tracer uses that too and it calls rcu_dereference_raw(). Is this acceptable for you? If so can you give me your acked-by, so that I can push this up to Linus. Otherwise, the system locks up when doing function tracing with too much RCU debug running. Thanks, -- Steve
