| /* |
| * This is the structure used to lay out an inode log item in the |
| * 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 When an inode log item gets superseded, |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. |
