[GFS2] Shrink gfs2_inode (7) - di_payload_format
This is almost never used. Its there for backward compatibility with GFS1. It doesn't need its own field since it can always be calculated from the inode mode & flags. This saves a bit more space in the gfs2_inode. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
