That means some subsystems will be worse as far as stable release support goes. That's not a problem: - some subsystems have people paid to do backports to LTS releases when patches don't apply; others don't, if the patch doesn't apply the bug is simply not fixed in LTS releases - some subsystems are worse than others even in "normal" releases :) >> (plus backports) is where the burden on maintainers should start and >> end.  I don't see the need to second guess them. > > This is similar to describing our CI infrastructure as "second > guessing": why are we second guessing authors and maintainers who are > obviously doing the right thing by testing their patches and reporting > issues to them? No, it's not the same. CI helps finding bugs before you have to waste time spending bisecting regressions across thousands of commits. The lack of stable tags _can_ certainly be a problem, but it solves itself sooner or later when people upgrade their kernel. > Are you saying that you have always gotten stable tags right? never > missed a stable tag where one should go? Of course I did, just like I have introduced bugs. But at least I try to do my best both at adding stable tags and at not introducing bugs. Paolo
