To be fair, I did not notice it, but I think that people who will miss it will have skipped 2 versions, in which case they can reasonably expect enough changes to be very careful when updating their config.

No, because I have no SATA disk ;-)

Yes I've noticed this one, and at least it was clearly visible !

Don't get me wrong, I'm not complaining. I just realized from previous post that options disappearing produce no warning on make oldconfig, and that it is easy to get trapped, even though there's nothing harmful.

Sometimes I do a diff between old and new config, and I do not notice that many changes. So maybe a simple report at the end saying "The following options have been removed" may catch people's attention when it lists something which looks like a driver they know they use.
Anyway, I don't have time to propose something in this area, and I know that talking is cheap, showing the code is another matter.
Cheers, Willy
