- * -Version 1 of this structure (XFS_LI_5_3_INODE) included up to the first

- * -Version 2 of this structure (XFS_LI_6_1_INODE) is currently the entire

- * -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
