McKenney" , linux-kernel@vger.kernel.org Subject: [PATCH] hashtable: add hash_for_each_possible_rcu_notrace() Date: Sat, 6 Jul 2013 14:16:50 +1000 Message-Id: <1373084210-27767-1-git-send-email-aik@ozlabs.ru> X-Mailer: git-send-email 1.8.3.2 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1648 Lines: 43 This adds hash_for_each_possible_rcu_notrace() which is basically a notrace clone of hash_for_each_possible_rcu() which cannot be used in real mode due to its tracing/debugging capability.
