  ocfs2_lock() will skip locks on file which has mode set to 02666. This
  is a problem in cases where the mode of the file is changed after a
  process has obtained a lock on the file.

  ocfs2_lock() should skip the check for mandatory locks when unlocking a
  file.

  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.

  Hook up ocfs2_flock(), using the new flock lock type in dlmglue.c. A new
  mount option, "localflocks" is added so that users can revert to old
  functionality as need be.
