6 fs-verity: read-only file-based authenticity protection
12 fs-verity (``fs/verity/``) is a support layer that filesystems can
13 hook into to support transparent integrity and authenticity protection
14 of read-only files. Currently, it is supported by the ext4, f2fs, and
15 btrfs filesystems. Like fscrypt, not too much filesystem-specific
16 code is needed to support fs-verity.
18 fs-verity is similar to `dm-verity
