McKenney" , Ingo Molnar , Linux Kernel Mailing List Subject: [PATCH] rcu: remove duplicate CONFIG_RCU_CPU_STALL_DETECTOR Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Impact: remove the old CONFIG_RCU_CPU_STALL_DETECTOR tree_rcu introduce CONFIG_RCU_CPU_STALL_DETECTOR again. These two are the same exactly except: the old one "depends on CLASSIC_RCU" the new one "depends on CLASSIC_RCU || TREE_RCU" This patch remove the old one.
