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. * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: f2fs: add support for IV_INO_LBLK_64 encryption policies ext4: add support for IV_INO_LBLK_64 encryption policies fscrypt: add support for IV_INO_LBLK_64 policies fscrypt: avoid data race on fscrypt_mode::logged_impl_name docs: ioctl-number: document fscrypt ioctl numbers fscrypt: zeroize fscrypt_info before freeing fscrypt: remove struct fscrypt_ctx fscrypt: invoke crypto API for ESSIV handling
