I'm submitting the bcachefs filesystem for review and inclusion. Included in this patch series are all the non fs/bcachefs/ patches. The entire tree, based on v6.3, may be found at: http://evilpiepirate.org/git/bcachefs.git bcachefs-for-upstream ---------------------------------------------------------------- bcachefs overview, status: Features: - too many to list Known bugs: - too many to list Status: - Snapshots have been declared stable; one serious bug report outstanding to look into, most users report it working well. These are RW btrfs-style snapshots, but with far better scalability and no scalability issues with sparse snapshots due to key level versioning. - Erasure coding is getting really close; hope to have it ready for users to beat on it by this summer. This is a novel RAID/erasure coding design with no write hole, and no fragmentation of writes (e.g. RAIDZ). - Tons of scalabality work finished over the past year, users are running it on 100 TB filesystems without complaint, waiting for first 1 PB user; next thing to address re: scalability is fsck/recovery memory usage. - Test infrastructure! Major project milestone, check out our test dashboard at https://evilpiepirate.org/~testdashboard/ci?branch=bcachefs Other project notes: irc::/irc.oftc.net/bcache is where most activity happens; I'm always there, and most code review happens there - I find the conversational format more productive. ------------------------------------------------ patches in this series: Christopher James Halse Rogers (1): stacktrace: Export stack_trace_save_tsk Daniel Hill (1): lib: add mean and variance module.
