Thanks!

There are two more that annoy me, but I don't know how to fix them:

ata_scsi_rbuf                                  -    4096   +4096
ata_force_param_buf                            -    4096   +4096

Gr{oetje,eeting}s,

                        Geert

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
