  Log:
   - Define a new flag for getblk(): GB_NOCREAT.  This flag causes getblk() to
     bail out if the buffer is not already present.
   - The buffer returned by incore() is not locked and should not be sent to
     brelse().  Use getblk() with the new GB_NOCREAT flag to preserve the
     desired semantics.
