Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

35 | /* | ||
36 | * This is the structure used to lay out an inode log item in the | ||
37 | * log. The size of the inline data/extents/b-tree root to be logged | ||
38 | * (if any) is indicated in the ilf_dsize field. Changes to this structure | ||
39 | * must be added on to the end. | ||
40 | * | ||
41 | * Convention for naming inode log item versions : The current version | ||
42 | * is always named XFS_LI_INODE. When an inode log item gets superseded, | ||
43 | * add the latest version of IRIX that will generate logs with that item | ||
44 | * to the version name. | ||
45 | * | ||
46 | * -Version 1 of this structure (XFS_LI_5_3_INODE) included up to the first | ||
47 | * union (ilf_u) field. This was released with IRIX 5.3-XFS. | ||
48 | * -Version 2 of this structure (XFS_LI_6_1_INODE) is currently the entire | ||
49 | * structure. This was released with IRIX 6.0.1-XFS and IRIX 6.1. | ||
50 | * -Version 3 of this structure (XFS_LI_INODE) is the same as version 2 | ||
51 | * so a new structure definition wasn't necessary. However, we had | ||
52 | * to add a new type because the inode cluster size changed from 4K | ||
53 | * to 8K and the version number had to be rev'ved to keep older kernels | ||
54 | * from trying to recover logs with the 8K buffers in them. The logging | ||
55 | * code can handle recovery on different-sized clusters now so hopefully | ||
56 | * this'll be the last time we need to change the inode log item just | ||
57 | * for a change in the inode cluster size. This new version was | ||
58 | * released with IRIX 6.2. | ||
