2933f9254a [GFS2] Shrink gfs2_inode (4) - di_uid/di_gid
Remove duplicate di_uid/di_gid fields in favour of using
inode->i_uid/inode->i_gid instead. This saves 8 bytes.

e7f14f4d09 [GFS2] Shrink gfs2_inode (2) - di_major/di_minor
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.

af339c0241 [GFS2] Shrink gfs2_inode (1) - di_header/di_num
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.

539e5d6b7a [GFS2] Change argument of gfs2_dinode_out
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.

48516ced21 [GFS2] Remove uneeded endian conversion
In many places GFS2 was calling the endian conversion routines
for an inode even when only a single field, or a few fields might
have changed. As a result we were copying lots of data needlessly.

This patch replaces those calls with conversion of just the
required fields in each case. This should be faster and easier
to understand. There are still other places which suffer from this
problem, but this is a start in the right direction.
