Miller" , Cong Wang To: netdev@vger.kernel.org Return-path: Received: from mx1.redhat.com ([209.132.183.28]:29150 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751151Ab2HJLZW (ORCPT ); Fri, 10 Aug 2012 07:25:22 -0400 Sender: netdev-owner@vger.kernel.org List-ID: V5: * Rename the local variable 'info' to 'vlan' * add another vlan cleanup patch V4: * rebase against net tree * fix a compile error in patch 9 * update patch 7 as Stephen suggested V3: * add more patches * update patch 7 as David suggested V2: * update patch 1/8 as Eric suggested * drop the bridge patch, add comments instead * add patch 8/8 This patchset fixes serval problems in netconsole and netpoll. I ran this patchset in my KVM guest with some netpoll test cases, even covered with some corner cases, everything worked as expected. BTW, my kernel config enables the following validatation options: CONFIG_DEBUG_ATOMIC_SLEEP=y CONFIG_PROVE_LOCKING=y CONFIG_PROVE_RCU=y CONFIG_LOCKDEP=y CONFIG_RCU_CPU_STALL_TIMEOUT=60 CONFIG_LOCKUP_DETECTOR=y CONFIG_HARDLOCKUP_DETECTOR=y Cc: "David S.
