  * log.  The size of the inline data/extents/b-tree root to be logged
  * (if any) is indicated in the ilf_dsize field.  Changes to this structure
  * must be added on to the end.
- *
- * Convention for naming inode log item versions :  The current version
- * is always named XFS_LI_INODE.  When an inode log item gets superseded,
- * add the latest version of IRIX that will generate logs with that item
- * to the version name.
- *
- * -Version 1 of this structure (XFS_LI_5_3_INODE) included up to the first
- *	union (ilf_u) field.  This was released with IRIX 5.3-XFS.
- * -Version 2 of this structure (XFS_LI_6_1_INODE) is currently the entire
- *	structure.  This was released with IRIX 6.0.1-XFS and IRIX 6.1.
- * -Version 3 of this structure (XFS_LI_INODE) is the same as version 2
- *	so a new structure definition wasn't necessary.  However, we had
- *	to add a new type because the inode cluster size changed from 4K
- *	to 8K and the version number had to be rev'ved to keep older kernels
- *	from trying to recover logs with the 8K buffers in them.  The logging
- *	code can handle recovery on different-sized clusters now so hopefully
- *	this'll be the last time we need to change the inode log item just
- *	for a change in the inode cluster size.  This new version was
- *	released with IRIX 6.2.
