From: Mingming Cao Subject: [EXT4 set 4][PATCH 2/5] i_version: Add hi 32 bit inode version on ext4 on-disk inode Date: Sun, 01 Jul 2007 03:37:16 -0400 Message-ID: <1183275436.4010.127.camel@localhost.localdomain> Reply-To: cmm@us.ibm.com Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-fsdevel@vger.kernel.org, linux-kernel@vger.kernel.org, linux-ext4@vger.kernel.org, nfsv4@linux-nfs.org Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: nfsv4-bounces@linux-nfs.org Errors-To: nfsv4-bounces@linux-nfs.org List-Id: linux-ext4.vger.kernel.org This patch adds a 32-bit i_version_hi field to ext4_inode, which can be used for 64-bit inode versions. This field will store the higher 32 bits of the version, while Jean Noel's patch has added support to store the lower 32-bits in osd1.linux1.l_i_version.
