Linux is about to lose a feature [Bcachefs (ofc)]

It looks likely that Overstreet has upset too many important, influential people, and hurt too many feelings — and as a result, Linux is not going to get a new next-gen copy-on-write filesystem. It's a significant technological loss, and it's all down to people not getting along, rather than the shared desire to create a better OS. ®

I don't like how this article is framed as if everyone else not tiptoeing around Kent is The Real Problem. He was given clear warnings and way more second chances than he deserved. He was (and still is) unable to follow the rules and control his temper, and everyone decided he's a lost cause - as is completely logical. Just because you have a cool toy doesn't mean everyone is forced to be your friend. Go play in your own sandbox until you learn to follow the rules like everyone else. Consider writing a giant apology letter and giving the Linux community the best gift of all: changed behavior.

The device working on BcacheFS is unreliable, and kind of a lazy dickhead. It's not a personality clash, the guy has been given the commit guidelines, just like every day else, and regularly skirts them and commits problematic code. If you did that in your real job, you would be fired.

Frankly, based on what people in this thread are saying, the developer is unable to follow proper procedures to submit code. I personally would not trust someone like this.

It's been going for a long time, I'm seriously surprised that it took so long. It's like having to explain over and over the same thing, and even if the person seems to be willing to cooperate in the moment of the discussion, the next time they do the same.
The author of the article doesn't seem too terribly stable either.

[Sarcasm] Yeah sure, a "personality clash." It's definitely a "large and unfortunate mistake" to drop a developer just because you don't like the way they routinely bollocks up established, reasoned software development practices. 🙄

C'mon, Reg, have a nap or something and cool off.

We still got BTRFS as our next-gen filesystem, we should be fine.

Only if you like "eventual consistency", in the sense of "eventually, your data is consistently gone".
- What are you people doing with your PCs? I don't mean it rude, I'm just curious. I admit I'm just regular home PC user, playing games, watching videos, doing some lame audio editing, nothing too serious. I just installed opensuse with btrfs some 4-5 years ago and never had single FS related problem since then. On the other hand it saved my ass multiple times either when I fucked something up or couple times when certain OS update didn't work well with my PC.
  I'm not saying it's bulletproof, shit happens all the time, it's just... Maybe I'm lucky? Just a fun fact: My PC at work with windows had way more problems (including filesystem ones) than I've had at home during said time.
- Correct me if I'm wrong but Bcachefs was in the same spot no?
  If anything, it's feature parity lol

Sorta related but these "next gen" FSs are pretty overrated on the performance benchmarks lots of groups like Phoronix do every kernel release.

BTRFS lags behind a ton compared to XFS, even though XFS was originally designed for large file throughput on servers.

Even EXT4 beats BcacheFS and BTRFS on several irl load benchmarks.

Only thing I've seen actually keep up is F2FS which iirc is the default on Android these days.

The point of these next gen file systems aren't raw performance, they are reliability, performance for specific cases, and reduced data usage. For example:
Copy on Write means it's very performant to create snapshots
incremental backups are much quicker
checksumming means the filesystem directly and reliably detects data corruption
built-in support for raid means a simplified setup and integration of scrubbing features into the filesystem, which can then take advantage of checksumming etc.
deduplication can automatically recognize duplicated data and as such reduce data use
These are things that tend to reduce performance, not increase it. Which is why, when performance on these filesystems stays the same or even increases, that's a major accomplishment.
The point of COW filesystems isn't performance. Comparing XFS and EXT4 to BTRFS/ZFS/Bcache is pointless.

Linux is about to lose a feature [Bcachefs (ofc)]– over a personality clash (ofc)
