* 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 When an inode log item gets superseded,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.
