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!

/*
|
|
* 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 When an inode log item gets superseded,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.
