    kernel - Attempt to fix shared/excl namecache deadlock
    
    * Attempt to fix a shared/excl namecache deadlock where the shared lock
      may block excessively waiting for other shared users to unlock when
      an exclusive request is pending.
    
    * Do a better job reporting the time delayed when blocked for an
      excessive period of time.
