Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt
Pull fscrypt updates from Eric Biggers: "Add an ioctl FS_IOC_GET_ENCRYPTION_NONCE which retrieves a file's encryption nonce. This makes it easier to write automated tests which verify that fscrypt is doing the encryption correctly" * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: ubifs: wire up FS_IOC_GET_ENCRYPTION_NONCE f2fs: wire up FS_IOC_GET_ENCRYPTION_NONCE ext4: wire up FS_IOC_GET_ENCRYPTION_NONCE fscrypt: add FS_IOC_GET_ENCRYPTION_NONCE ioctl
