Lesson plan

Bcachefs

Bcachefs is a copy-on-write (COW) file system for Linux-based operating systems. It is intended to compete with the modern features of ZFS or Btrfs. It was first announced it in 2015, and added to the Linux kernel beginning with version 6.7 in 2024. In June 2025, Linus Torvalds announced bcachefs would be ejected from the kernel as a result of repeated violations of kernel development guidelines. In August 2025, bcachefs status was changed from 'Supported' to 'Externally maintained'. As of late September 2025, Linus Torvalds has removed all Bcachefs code from the Linux Kernel, beginning with version 6.18. It is now available as an external module.
