EFS support for linux 2.2

[Al Smith <Al.Smith@aeschi.ch.eu.org>]

Support for EFS filesystems (both on CD, and on hard disk partitions) is
available from the anonymous sgi/linux CVS server, and from
http://aeschi.ch.eu.org/efs/. The code can be either compiled separately
and inserted as a module, or integrated into the kernel by applying a
patch.

This support is still experimental - please let me know if you try it,
whether you encounter problems or not.
