Linux 7.3 introduces a significant cleanup to the FSCRYPT file-system encryption framework, simplifying the codebase and enabling future feature additions such as Btrfs encryption support.
FSCRYPT currently provides per-directory transparent encryption for EXT4, F2FS, and CephFS, and this cleanup removes structural barriers that have apparently prevented extending that support to additional filesystems like Btrfs. Engineers working with encrypted filesystems on Linux should track what new capabilities become possible after this refactor lands.
