| |
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.
