With all due respect, "approved by Linus" is not an argument :-) I get that Linus can make the "ultimate decision" but in argumentation I'm not a strong believer of authority based decision making process.

To add, some companies and other organizations prefer Jenkins. This one fit for all strategy is somewhat short-sighted. Also running Gitlab tasks locally is possible but is heavy-lifting. Can we then agree that any CI changes can be sent untested to LKML if a patch set needs to reflect on those? It's not reasonable to except local runs Gitlab from individuals for patch sets. It makes our lives more difficult, not easier. All maintainers I know test their patches for the most part with BuildRoot, distro VM's and stuff like that. Not claiming that they don't exist, but never heard of kernel maintainer who uses Gitlab as their main kernel testing tool. > Sure, a script could be contributed too, but the value of this contribution is > a ready-made integration.

Are you dead seriously claiming that DevOps engineers could not handle well defined CI scripts and bind to whatever CI makes sense to them? o_O > > BTW, here's the talk we gave at last year's LPC regarding current use of > GitLab in the kernel and surrounding community: > > https://lpc.events/event/18/contributions/1728/ This patch set should make the case, not an old presentation. > Nick BR, Jarkko
