  SVN rev 195294 on 2009-07-02 18:02:55Z by kib
  
  In vn_vget_ino() and their inline equivalents, mnt_ref() the mount point
  around the sequence that drop vnode lock and then busies the mount point.
  Not having vlocked node or direct reference to the mp allows for the
  forced unmount to proceed, making mp unmounted or reused.
