    sys/kern             vfs_vnops.c 
  Log:
   - Don't acquire the vnode interlock in _vn_lock() unless no lock type
     is requested.  Handle this case specially before the while loop.
   - Use the held vnode lock to check for VI_DOOMED.  The vnode lock and
     interlock must both be held to set VI_DOOMED so either one held, even
     shared, is sufficient to check it.
