 - Don't allow calls to vn_lock() with no lock type requested.  Callers    which simply want a reference should use vref().  Callers which want    to check validity need to hold a lock while performing any action    based on that validity.  vn_lock() would always release the interlock    before returning making any action synchronous with the validity check    impossible.
