Bcachefs – A New COW Filesystem

From https://bcachefs.org:

Bcachefs is an advanced new filesystem for Linux, with an emphasis on reliability and robustness and the complete set of features one would expect from a modern filesystem.

- Copy on write (COW) - like zfs or btrfs

- Full data and metadata checksumming

- Multiple devices

- Replication

- Erasure coding (only feature not quite stable)

- Caching

- Compression

- Encryption

- Snapshots

- Scalable - has been tested to 50+ TB, will eventually scale far higher

- Already working and stable, with a small community of users

This is an email to linux kernel mailing list where Kent Overstreet asks for a review and inclusion of bcachefs filesystem.
