I can now confirm that bcachefs is getting stable and the test cases 
with intentionally data corruption (simulation of a real world case I 
had) gets bcachefs back to a consistent state (after 2 runs of: bcachefs 
fsck -f -y ${DEV}). That's a base requirement for a stable filesystem. 
Version of bcachefs-tools is git 
530e8ade4e6af7d152f4f79bf9f2b9dec6441f2b and kernel is 
6.16.0-200.fc42.x86_64.

See for details, I made data corruption even worser with running the 
destroy script 5x:

Great work Kent and the other contributors.

Unfortunately btrfs can't be repaired to a consistent state with the 
same testcase. I'd like to be that testcase fixed also for BTRFS as a 
stable filesystem (versions: 6.16.0-200.fc42.x86_64, btrfs-progs v6.15, 
-EXPERIMENTAL -INJECT -STATIC +LZO +ZSTD +UDEV +FSVERITY +ZONED 
CRYPTO=libgcrypt).

(I reported that already far in the past on the mailing list, see here: 
https://lore.kernel.org/linux-btrfs/[email protected]/).

Thnx.

Ciao,
