From: Sweet Tea Dorminy <sweettea-kernel@dorminy.me>
Right now there isn't a way to encrypt things that aren't either
filenames in directories or data on blocks on disk with extent
encryption, so for now, disable verity usage with encryption on btrfs.
fscrypt with fsverity should be possible and it can be implemented
in the future.
