Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt
Pull fscrypt updates from Eric Biggers:
- Add the IV_INO_LBLK_64 encryption policy flag which modifies the
encryption to be optimized for UFS inline encryption hardware.
- For AES-128-CBC, use the crypto API's implementation of ESSIV (which
was added in 5.4) rather than doing ESSIV manually.
- A few other cleanups.
