From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nick Piggin Subject: [announce] rcu-walk and dcache scaling tree update Date: Wed, 15 Dec 2010 21:22:26 +1100 Message-ID: <20101215102226.GA9093@amd> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: linux-fsdevel@vger.kernel.org, linux-kernel@vger.kernel.org Return-path: Received: from ipmail06.adl2.internode.on.net ([150.101.137.129]:54662 "EHLO ipmail06.adl2.internode.on.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755129Ab0LPC1K (ORCPT ); Wed, 15 Dec 2010 21:27:10 -0500 Content-Disposition: inline Sender: linux-fsdevel-owner@vger.kernel.org List-ID: I'm rebasing the tree, because I don't expect anybody to be basing downstream work on it, I hope that doesn't cause anybody pain. Git tree is here: git://git.kernel.org/pub/scm/linux/kernel/git/npiggin/linux-npiggin.git Branch is: vfs-scale-working Changes since last posting: * Added mntget/mntput scaling patch. I think this is important for testers because it significantly increases parallelism through the dcache and path walk. So both performance and races will get better test coverage. * Missing vfs.txt documentation for new _rcu dentry and inode ops. * Large improvements to Documentation/filesystems/path-walk.txt * Improved some changelogs * Added AMD fam10h numbers to ``memcmp optimisation'' changelog, and Westmere numbers to ``prefetch inode'' optimisation changelog. The AMD doesn't get such a big boost as the Intel CPU when avoiding rep cmp, but does get a small improvement. Thanks, Nick
