The Ocfs2 userspace cluster stack module already uses fs/dlm as the\nunderlying lock manager, so I only had to add the right calls.\n\nCluster-aware POSIX locks (\"plocks\") can be turned off by the same means at\nUNIX locks - mount with \u0027noflocks\u0027, or create a local-only Ocfs2 volume.\nInternally, the file system uses two sets of file_operations, depending on\nwhether cluster aware plocks is required. This turns out to be easier than\nimplementing local-only versions of -\u003elock.\n\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n"
