  SVN rev 194289 on 2009-06-16 13:05:34Z by emaste
  
  MFC part of r166182 and 179670.
  
    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.
