The DCL-only patch applies after the first one (OSDL patch) and has
enhancements that are applicable mostly to NUMA systems used in
data center systems.
The latest release is available in downloadable patches from
http://sourceforge.net/projects/osdldcl
or public BitKeeper repositories

Getting Involved
----------------
If interested in development of DCL, please subscribe to the mailing
list at http://lists.osdl.org/mailman/listinfo/dcl_discussion .
This kernel has been built and run on a small set of machines, SMP
and UP. Testers are encouraged to exercise the features. If a
problem is found, please compare the result with a standard 2.5.51
kernel. Please report any problems or successes to the mailing list.
Developers are encouraged to send any enhancements or bug fix
patches. Patches should be tested by using the OSDL Scalable Test
Platform (STP) and Patch Lifecycle Manager (PLM) facilities.
