From 6d3ebaae7c20128bfa6965a8d5cee0d1deea8486 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 28 Nov 2014 14:24:06 +1100 Subject: xfs: merge xfs_dinode.h into xfs_format.h More consolidatation for the on-disk format defintions. Note that the XFS_IS_REALTIME_INODE moves to xfs_linux.h instead as it is not related to the on disk format, but depends on a CONFIG_ option.
