The meta_header for an ondisk rgrp never changes, so there is no point
copying it in and back out to disk. Also there is no reason to keep
a copy for each rgrp in memory.
The code already checks to ensure that the header is correct before
it calls the routine to copy the data in, so that we don't even need
to check whether its correct on disk in the functions in ondisk.c

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.

Remove the di_[amc]time fields and use inode->i_[amc]time
fields instead. This saves 24 bytes from the gfs2_inode.

Remove the di_nlink field in favour of inode->i_nlink and
update the nlink handling to use the proper macros. This
saves 4 bytes.

Remove duplicate di_uid/di_gid fields in favour of using
inode->i_uid/inode->i_gid instead. This saves 8 bytes.

This removes the duplicate di_mode field in favour of using the
inode->i_mode field. This saves 4 bytes.

This removes the device numbers from this structure by using
inode->i_rdev instead. It also cleans up the code in gfs2_mknod.
It results in shrinking the gfs2_inode by 8 bytes.

The metadata header doesn't need to be stored in the incore
struct gfs2_inode since its constant, and this patch removes it.
Also, there is already a field for the inode's number in the
struct gfs2_inode, so we don't need one in struct gfs2_dinode_host
as well.
This saves 28 bytes of space in the struct gfs2_inode.

Change argument for gfs2_dinode_print in order to prepare
for removal of duplicate fields between struct inode and
struct gfs2_dinode_host.

gfs2_dinode_in() is only ever called from one place, so move it
to that place (in inode.c) and make it static.

This is a preliminary patch to enable the removal of fields
in gfs2_dinode_host which are duplicated in struct inode.

Everywhere this was called, a struct gfs2_inode was available,
but despite that, it was always called with a struct gfs2_dinode
as an argument. By making this change it paves the way to start
eliminating fields duplicated between the kernel's struct inode
and the struct gfs2_dinode.

Annotate scalar ones, kill completely unused.

Annotated scalar fields, dropped unused ones. Note that
it's not at all obvious that we want to convert all of them
to host-endian...

The latter is used as part of gfs2-private part of struct inode.
It actually stores a lot of fields differently; for now the
declaration is just cloned, inode field is swtiched and changes
propagated.
