The fundamental design is mostly unchanged.  What you might now want to
bother reading of the original documents are:

 dir_design.pdf - the dir code has been completely replaced
 threads.pdf - this is totally IRIX specific
 scaffold.pdf - again mostly IRIX specific
 message.pdf - no idea what this is at all, I never saw traces of this
 in XFS

For all others there's quite a bit of IRIXism in there.

Is there anything specific you're looking for?
