+	  separate area of disk space where only file data is stored.  It was
+	  originally designed to provide deterministic data rates suitable
+	  for media streaming applications, but is also useful as a generic

- * -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.
