Linus Torvalds has changed the support status of bcachefs in the Linux kernel to 'externally maintained'. The note on the change states that this decision was made after prolonged discussions, both public and private. Essentially, the new status means that no further changes will be accepted for Bcachefs, but this filesystem will remain in a frozen state within the main body of the kernel. Until Kent Overstreet can demonstrably prove the ability to correctly interact with other kernel developers and follow established development rules, further development of Bcachefs will take place outside the kernel codebase.
