  Log:
  SVN rev 223312 on 2011-06-19 23:54:01Z by rmacklem
  
  Fix a number of places where the new NFS server did not
  lock the mutex when manipulating rc_flag in the DRC cache.
  This is believed to fix a hung server that was reported
  to the freebsd-fs@ list on June 9 under the subject heading
  "New NFS server stress test hang", where all the threads
  were waiting for the RC_LOCKED flag to clear.
  
  Tested by:      jwd at slowblink.com
