    sys/fs/nullfs        null_vnops.c 
  Log:
  MFC 1.88 (by ssouhlal):
  
  Use vput() instead of vrele() in null_reclaim() since the lower vnode
  is locked.
  
  MFC 1.89 (by kan):
  
  Handle a race condition where NULLFS vnode can be cleaned while threads
  can still be asleep waiting for lowervp lock.

  (rev. 1.89 is an early MFC for inclusion in the upcoming 6.0-BETA5)
