Same. I liked many of its features (actually, all features, see https://bcachefs.org) and I was waiting for it to become usable, but I guess that day will never come now?

So, the alternative is ZFS only, maybe HAMMER2. HAMMER2 does not look too bad either, except you need DragonflyBSD for that.

What I expect to happen is that bcachefs stabilizes outside of mainline, and after that, it can be merged back because no large patches = not much drama potential.

My concern is that historically some of the conflict over bcachefs was because work on it touched code outside the filesystem area. If a year from now they show up and say "okay, here's the new bcachefs code that's 100% formally verified and has zero bugs and is good to go!", then it still could fail to get merged because they rewrote parts of (say) the block device system and the maintainers of that part of the kernel don't like the changes.

		Hey, the block i/o subsystem is at least connected! Kent also wrote a brand-new locking system: https://lwn.net/Articles/755164/

		I didn't forget about these things, but I was under the impression that they had been resolved one way or another.

It's not unusable, I use it on a spare computer for fun, cuz I want tiering of SSD + HDDs. And this doesn't mean development has stopped, just not done in the kernel.

True, I did not mean to say usable, I meant to say that "officially supported", but I will give it a go with a custom built kernel sooner or later.

For how long have you been using it? Any issues? Any favorite feature(s) in particular?

		I've been using it about a year or so. Like I said, the 'killer feature' for me is tiering. I'm not using it on my main computer, but a spare parts computer with whatever storage I have laying around thrown into it, so being able to combine a 3TB HDD with a 1/2 TB SSD. All the storage stays usable, and I get better performance. Not perfect though. Performance at times doesn't seem better than just SSD, though I didn't really test that and I'm not sure if it's just hitting the HDD at those times. And there was a kernel version that didn't boot, though I'm staying on the bleeding edge with Arch Linux.
