  f2fs: add support for IV_INO_LBLK_64 encryption policies (2019-11-06 12:34:42 -0800)

----------------------------------------------------------------

- 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.

----------------------------------------------------------------
Eric Biggers (8):
      fscrypt: invoke crypto API for ESSIV handling
      fscrypt: remove struct fscrypt_ctx
      fscrypt: zeroize fscrypt_info before freeing
      docs: ioctl-number: document fscrypt ioctl numbers
      fscrypt: avoid data race on fscrypt_mode::logged_impl_name
      fscrypt: add support for IV_INO_LBLK_64 policies
      ext4: add support for IV_INO_LBLK_64 encryption policies
      f2fs: add support for IV_INO_LBLK_64 encryption policies
