I don't think we should use a number cap here, but rather look at the regression rate: how many patches broke something?
Since the rate we're seeing now with AUTOSEL is similar to what we were seeing before AUTOSEL, what's the problem it's causing?
Regression rate should not be the only criteria.
More patches mean bigger chance customer's patches will have a conflict with something in -stable, for example.
Out of tree patches can't be a consideration here. There are no guarantees for out of tree code, ever.
Out of tree code is not consideration for mainline, agreed. Stable should be different.
This is a discussion we could have with in right forum, but FYI stable doesn't even guarantee KABI compatibility between minor versions at this point.
Stable should be useful base for distributions. They carry out of tree patches, and yes, you should try to make their lives easy.
How do you know I already don't do that?
But no, in the end, it's not my job to make their life easier if they are off in their own corner never providing me feedback or help. For those companies/distros/SoCs that do provide that feedback, I am glad to work with them.
As proof of that, there are at least 3 "major" SoC vendors that have been merging every one of the stable releases into their internal trees for the past 6+ months now. I get reports when they do the merge and test, and so far, we have only had 1 regression. And that regression was because that SoC vendor forgot to upstream a patch that they had in their internal tree (i.e. they fixed it a while ago but forgot to tell anyone else, nothing we can do about that.)
So if you are a distro/company/whatever that takes stable releases, and have run into problems, please let me know, and I will be glad to work with you.
If you are not that, then please don't attempt to speak for them...
thanks,
