c87a9ae705 ocfs2: temporarily disable automatic lock migration 
Now we never change the owner of a lock resource until unmount or node
death. This will be re-enabled once some issues in the algorithm used have
been resolved.

82353b594c [PATCH] This patch contains the following cleanups: 
- cluster/sys.c: make needlessly global code static
- dlm/: "extern" declarations for variables belong into header files
        (and in this case, they are already in dlmdomain.h)

6714d8e86b [PATCH] OCFS2: The Second Oracle Cluster Filesystem 
A distributed lock manager built with the cluster file system use case
in mind. The OCFS2 dlm exposes a VMS style API, though things have
been simplified internally. The only lock levels implemented currently
are NLMODE, PRMODE and EXMODE.
