Bcache File-System Has Initial Encryption Patches

It's been a while since last having anything to talk about with regard to Bcachefs as a file-system aiming for speed while having ZFS/Btrfs-like capabilities and being spun out of the Bcache caching code. This file-system now has tentative patches for complete encryption support.

Published earlier this month by Bcache developer Kent Overstreet is encryption support for the whole Bcachefs file-system. These preliminary patches were published for review and encrypt the entire file-system using ChaCha20/Poly1305. There is the support currently while creating a new Bcachefs file-system but support for an existing file-system is in the midsts of being worked on. This encryption code also doesn't support per-directory encryption.

If you are at all interested in Bcache(fs) and/or Linux file-system technologies, see this mailing list thread about the Bcachefs file-system encryption support.
