This directory includes an XFS papers, current and historical.
These documents do not necessarily reflect the current state of
XFS in IRIX or what will be XFS in Linux.
These documents are a good source for studying 
XFS, but one should keep in mind some of the XFS features 
may have changed since these documents were written.
SGI plans to work on up-to-date Linux-XFS design documents
to replace these historical, and now inaccurate documents.
Until then, these are a reasonable place from which to start
to learn about XFS.
 
The files are in a gzipped, tar, Adobe PDF or text format
which you may download via either of:

	o http:  http://oss.sgi.com/projects/xfs/
	o ftp:   ftp://oss.sgi.com/www/projects/xfs/

(ftp usually works better for big files since it can be
  restarted in case of timeouts or other mid-transfer failures)

------- ------- ------- ------- ------- ------- -------

Before SGI can distribute additional XFS code,
the original IRIX-XFS code needs to be "cleaned"
of legal encumbrances.  It also needs to be ported
from the IRIX-XFS source base to the Linux-XFS source base.

Please bear with us as we complete this process.
