Revision 1.22, Fri Mar 31 20:05:38 1995 UTC (22 years, 6 months ago) by doucette
Add an #ident line. Use struct xxx * instead of xxx_t * in xfs header files to avoid unnecessary dependencies between header files. |

* 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.
*
* -Version 1 of this structure (XFS_LI_OINODE) included up to the first
* union (ilf_u) field. This was released with IRIX 5.3-XFS.
* -Version 2 of this structure (XFS_LI_INODE) is currently the entire
* structure. This was released with IRIX 6.0.1-XFS and IRIX 6.1.
