Peter, I am sorry that I have focused recently on making the qspinlock patch works with virtualization and it is easier for me to based off on my patch initially. Now the PV part is almost done, I will apply them on top of your patch. Hopefully, I will get a new patch out sometime next week. I am really sorry if you have bad feeling about it. I do not mean to discredit you on your effort to make the qspinlock patch better. I really appreciate your input and would like to work with you on this patch as well as other future patches. -Longman From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from g2t2354.austin.hp.com ([15.217.128.53]:42791 "EHLO g2t2354.austin.hp.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752067AbaDDO7g (ORCPT ); Fri, 4 Apr 2014 10:59:36 -0400 Message-ID: <533EC8BD.8080601@hp.com> Date: Fri, 04 Apr 2014 10:59:09 -0400 From: Waiman Long MIME-Version: 1.0 Subject: Re: [PATCH v8 01/10] qspinlock: A generic 4-byte queue spinlock implementation References: <1396445259-27670-1-git-send-email-Waiman.Long@hp.com> <1396445259-27670-2-git-send-email-Waiman.Long@hp.com> <20140404130012.GE10526@twins.programming.kicks-ass.net> In-Reply-To: <20140404130012.GE10526@twins.programming.kicks-ass.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-arch-owner@vger.kernel.org List-ID: To: Peter Zijlstra Cc: Thomas Gleixner , Ingo Molnar , "H.
