Linux kernel 6.7 has been released. The main change in this version is the new file system — bcachefs.
The developers claim the following features for this file system:
- copy-on-write (COW), similar to ZFS or btrfs;
- checksums for all files and directories;
- support for multiple devices;
- replication;
- fault-tolerant coding (not yet stable);
- caching;
- compression;
- encryption;
- snapshots;
- support for no COW mode;
- links;
- extended attributes, ACL, quotas;
- high performance.
Other changes:
- Work has begun on the implementation of futex(2) (fast mutex in user space).
- Support for RAID stripe tree has been added in btrfs.
- Improvements in io_uring.
- Support for authentication in TCP has been added.
