ocfs2: Allow selection of cluster plug-ins.
ocfs2 now supports plug-ins for the classic O2CB stack as well as userspace cluster stacks in conjunction with fs/dlm. This allows zero, one, or both of the plug-ins to be selected in Kconfig. For local mounts (non-clustered), neither plug-in is needed. Both plugins can be loaded at one time, the runtime will select the one needed for the cluster systme in use.

+ depends on OCFS2_FS
+ default y
+ help
+ OCFS2 includes a simple kernelspace clustering package, the OCFS2
+ Cluster Base. It only requires a very small userspace component
+ to configure it. This comes with the standard ocfs2-tools package.
+ O2CB is limited to maintaining a cluster for OCFS2 file systems.
+ It cannot manage any other cluster applications.
+
+ It is always safe to say Y here, as the clustering method is
+ run-time selectable.

+ default y
+ help
+ This option will allow OCFS2 to use userspace clustering services
+ in conjunction with the DLM in fs/dlm. If you are using a
+ userspace cluster manager, say Y here.
+
+ It is safe to say Y, as the clustering method is run-time
