I don't really remember where if found this patch, i came accross it somewhere
in 1999, its written by Bill Dorsey and Bill Soley.

This is the patch you will need if you want to run CFS (Cryptographic File 
System) on Solaris 7 or later (verified on Solaris 8 and Solaris 7).

If you want more information about Sun Microsystems CFS (As in Cache FS)
you should take a look at http://docs.sun.com, they have everything
you need.
