  SVN rev 179670 on 2008-06-09 10:31:38Z by kib
  Provide the mutual exclusion between the nfs export list modifications
  and nfs requests processing. Lockmgr lock provides the shared locking for
  nfs requests, while exclusive mode is used for modifications. The writer
  starvation is handled by lockmgr too.
