  fscrypt: add support for IV_INO_LBLK_32 policies (2020-05-19 09:34:18 -0700)

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

- Add the IV_INO_LBLK_32 encryption policy flag which modifies the
  encryption to be optimized for eMMC inline encryption hardware.

- Make the test_dummy_encryption mount option for ext4 and f2fs support
  v2 encryption policies.

- Fix kerneldoc warnings and some coding style inconsistencies.

There will be merge conflicts with the ext4 and f2fs trees due to the
test_dummy_encryption change, but the resolutions are straightforward.

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