  Modified files:
    sys/kern             vfs_vnops.c 
  Log:
   - 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.
