  Modified:    sys/miscfs/union  union_vnops.c
  Log:
  Dirty change in union_lock().  Sometimes upper vnode is locked without
  UN_ULOCK flag.  This shows a locking violation but I couldn't find the
  reason UN_ULOCK is not set or upper vnode is not unlocked.  I added
  the code that detect this case and adjust un_flags.  DIAGNOSTIC kernel
  doesn't adjust un_flags, but just panic here to help debug by kernel
  hackers.
