  Log:
  MFC: Store a reference to the parent directory's vnode instead of its
  smbnode to avoid a use-after-free bug causing a panic when a smbfs mount
  is forcefully unmounted.
  
  Keep trying to flush the vnode list for the mount while some are still
  busy and we are making progress towards making them not busy. This stops
  attempts to unmount idle smbfs mounts failing with EBUSY.
