After three years of negotiations, Linus Torvalds accepted has accepted the bcachefs file system into Linux 6.7.
The development was carried out by Kent Overstreet over the past ten years. Functionally, bcachefs is similar to ZFS and btrfs, but the author claims that the design of the file system allows for a higher level of performance. For example, unlike btrfs, snapshots , but directly access memory. employ the COW technology, which eliminates the overhead of copying during writes to already allocated extents.
