Yes, get the latest dlm source (and gfs2 while you're at it) from a
2.6.21-rc kernel.  I usually do something like this as a shortcut:

  cp linux-2.6.21-rc/fs/dlm/* linux-2.6.20/fs/dlm/
  cp linux-2.6.21-rc/fs/gfs2/* linux-2.6.20/fs/gfs2/
  cp linux-2.6.21-rc/fs/gfs2/locking/dlm/* linux-2.6.20/fs/gfs2/locking/dlm/

No guarantees, but it often works and saves a bit of effort.
