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
