Pull dlm updates from David Teigland:
 "This set includes some minor fixes and improvements.  The one large
  patch addresses the special "nodir" mode, which has been a long
  neglected proof of concept, but with these fixes seems to be quite
  usable.  It allows the resource master to be assigned statically
  instead of dynamically, which can improve performance if there is
  little locality and most resources are shared."
