Added notes about jfs-dmapi-2.6.7-additional

June 8, 2004

To make this version of dmapi work with JFS you'll first
need the JFS dmapi patch then add the corresponding jfs-dmapi-*-additional
patch from this directory.

The JFS dmapi patches can be found at IBM's website.  Their patch will make
JFS dmapi-capable, and will include a JFS-specific version of the dmapi core
in fs/jfs/dmapi:

http://www-124.ibm.com/developer/opensource/jfs/project/pub/dmapi/

Then, from this fs/dmapi/PATCHES directory add on the corresponding
jfs-dmapi-*-additional patch.  This patch will convert JFS to use this unified
version of DMAPI.

Then use the same libdm that you use with your XFS dmapi applications.  You
should have libdm from dmapi-2.2.0 or later.

With these patches this unified DMAPI can manage XFS and JFS filesystems at
the same time, however SGI has not tested JFS with DMAPI.
