Concerns about general policy need to be handled separately from individual cases. You needed to play along, advocate for your position, explain your position (e.g. demonstrate how your processes eliminate certain classes of errors; or find some objective way to measure QA problems and present the stats), and push for a holistic process change that supports your use-case. That process change would need input from other people, and might end up very different to your original proposal, but it could have happened. Instead, you've burned (and continue to burn) bridges.

Linus's job is not to make the very next version of the kernel as good as it can be. It's to keep the whole system of Linux kernel maintenance going. (Maintaining the quality of the next version is almost a side-effect.) Asking him to make frequent exceptions to process is the equivalent of going "this filesystem is making poor decisions: let's hex-edit /dev/sda to allocate the blocks better". Your priority is making the next version of bcachefs as good as it can be, and you're confident that merging your patchsets won't break the kernel, but that's entirely irrelevant.

You have missed the point by a mile.

You're arguing from a false premise here. No exceptions were needed or required, bcachefs was being singled out because he and the other maintainers involved had no real interest in the end goal of getting a stable, reliable, trustworthy modern filesystem.

The discussions, public and private - just like you're doing here - always managed to veer away from engineering concerns; people were more concerned with politics, "playing the game", and - I'm not joking here - undermining me as maintainer; demanding for someone else to take over.

Basic stuff like QA procedure and how we prioritize patches never entered into it, even as I repeatedly laid that stuff out.

No, that is very much the point here. bcachefs has always had one of the better track records at avoiding regressions and quickly handling them when they do get through, and was being singled out as if something was going horribly awry anyways. That needs an explanation, but one was never given.

Look, from the way you've been arguing things - have you been getting your background from youtube commentators? You have a pretty one sided take, and you're pushing that point of view really hard when talking to the person who's actually been in the middle of it for the past two years.

Maybe you should reevaluate that.

Bureaucracies run on process. You call that "politics", but (when arguing with programmers) I call it code. The Linux kernel project is a bureaucracy.

I'm sure you're familiar with "separation of concerns" in programming: it's the same principle. My experience of bureaucracies is experience, but I'm sure most good books on the topic will have a paragraph or chapter on this.

> bcachefs was being singled out because he and the other maintainers involved had no real interest in the end goal of getting a stable, reliable, trustworthy modern filesystem.

I imagine they would dispute that.

> No exceptions were needed or required,

I know that Linus Torvalds would dispute that. In this HN thread and elsewhere, you've made good arguments that treating your approach as an exception is not warranted, and that your approach is better, but you surely aren't claiming that your approach is the usual approach for kernel development?

> undermining me as maintainer

Part of the job is dealing with Linus Torvalds. You're not good at that. It would make sense for you to focus on architecture, programming, making bcachefs great, and to let someone else deal with submitting patches to the kernel, or arguing those technical arguments where you're right, but aren't getting listened to.

People are "more concerned with politics" than with engineering concerns because the problem is not with your engineering.

> bcachefs has always had one of the better track records at avoiding regressions and quickly handling them when they do get through

That's not relevant. I know that you don't see that it's not relevant: that's why I'm saying it's not relevant.

> have you been getting your background from youtube commentators?

No, but I'm used to disputes of this nature, and I'm used to dealing with unreasonable people. You believe that others are being unreasonable, but you're not following an effective strategy for dealing with unreasonable people. I am attempting to give advice, because I want bcachefs in the kernel, and I haven't a hope of changing Linus Torvalds' mind, but I have half a hope of changing yours.

Rule one of dealing with unreasonable people is to pick your battles. How many times have I said "dispute" or "argument" in this comment? How many times have these been worthy disputes? Even if I've completely mischaracterised the overall situation, surely you can't claim that every argument you've had on the LKML or in LWN comments has been worth bcachefs being removed from the kernel.

Look, it wasn't just this one thing. There had been entirely too many arguments over bugfixes, with the sole justification on Linus's end being "it's experimental garbage that no one should be using".

I can't ship and support a filesystem under those circumstances.

The "support" angle is one you and a lot of other people are missing. Supporting it is critical to stabilizing, and we can't close the loop with users if we can't ship bugfixes.

Given the past history with btrfs, this is of primary concern.

You've been looking for a compromise position, and that's understandable, but sometimes the only reasonable compromise is "less stupidity, or we go our separate ways".

The breaking point was, in the private maintainer thread, a page and a half rant from Linus on how he doesn't trust my judgement, and then immediately after that another rant on how - supposedly - everyone in the kernel community hates me and wants me gone.

Not joking. You can go over everything I've ever said on LKML, including the CoC incident, and nothing rises to that level. I really just want to be done with that sort of toxicity.

I know you and a lot of other people wanted bcachefs to be upstream, and it's not an ideal situation, but there are limits to what I'm willing to put up with.

Now, we just need to be looking forward. The DKMS transition has been going smoothly, more people are getting involved, everyone's fully committed to making this work and I still have my funding.

It's going to be ok, we don't need to have everything riding on making it work with the kernel community.

And now, you guys don't have to worry about me burning out on the kernel community and losing my last vestiges of sanity and going off to live in the mountains and herd goats :)
