      ocfs2: POSIX file locks support · 53da4939
      Mark Fasheh authored
      This is actually pretty easy since fs/dlm already handles the bulk of the
      work. The Ocfs2 userspace cluster stack module already uses fs/dlm as the
      underlying lock manager, so I only had to add the right calls.
      
      Cluster-aware POSIX locks ("plocks") can be turned off by the same means at
      UNIX locks - mount with 'noflocks', or create a local-only Ocfs2 volume.
      Internally, the file system uses two sets of file_operations, depending on
      whether cluster aware plocks is required. This turns out to be easier than
      implementing local-only versions of ->lock.
