  Do not keep parent directory locked while calling VFS_ROOT to traverse mount
  points in lookup(). The lock can be dropped safely around VFS_ROOT because
  LOCKPARENT semantics with child and perent vnodes coming from different FSes
  does not really have any meaningful use. On the other hard, this prevents
  easily triggered deadlock on systems using automounter daemon.
