So, as long as it seems nobody had a strong argument against this
patch, what do you think about me committing it?
We can further refine later if we think it is the case.

Also, I think that Matt's patch should be committed just after this
one (and possibly we should investigate a similar add-on for the ata
counterpart too?).

Thanks,
Attilio
