From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michal Hocko Subject: mmotm git tree since-4.9 branch created (was: mmotm 2016-12-12-17-02 uploaded) Date: Tue, 13 Dec 2016 14:52:29 +0100 Message-ID: <20161213135229.GB7803@dhcp22.suse.cz> References: <584f48d9.dfBrttZ3CZ8rJ1M2%akpm@linux-foundation.org> Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Return-path: Received: from mail-wm0-f67.google.com ([74.125.82.67]:32771 "EHLO mail-wm0-f67.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932883AbcLMNwd (ORCPT ); Tue, 13 Dec 2016 08:52:33 -0500 Content-Disposition: inline In-Reply-To: <584f48d9.dfBrttZ3CZ8rJ1M2%akpm@linux-foundation.org> Sender: linux-next-owner@vger.kernel.org List-ID: To: akpm@linux-foundation.org Cc: mm-commits@vger.kernel.org, linux-kernel@vger.kernel.org, linux-mm@kvack.org, linux-fsdevel@vger.kernel.org, linux-next@vger.kernel.org, sfr@canb.auug.org.au, broonie@kernel.org I have just created since-4.9 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v4.9 tag in Linus tree and mmotm-2016-12-12-17-02. Tracking all the dax related changes was quite challenging but I hope I have it all. I have pulled from - Dave's tree: dax-4.10-iomap-pmd, xfs-4.10-misc-fixes-2, iomap-4.10-directio - Ted's tree: dev - Dan's tree: libnvdimm-for-next Let me know if I am missing anything, please. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347) The shortlog says: Alexey Dobriyan (8): proc: make struct pid_entry::len unsigned proc:
