From 56cea2d088811b8cf7d2893e29bcf369a912de69 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 12 Mar 2013 23:30:36 +1100 Subject: [PATCH] xfs: take inode version into account in XFS_LITINO Add a version argument to XFS_LITINO so that it can return different values depending on the inode version. This is required for the upcoming v3 inodes with a larger fixed layout dinode.
