This patchset introduces support decryption for Android 11. In this update we deprecate ext4crypt. To specify the policy version to use, use TW_USE_FSCRYPT_POLICY := 1 or TW_USE_FSCRYPT_POLICY := 2. By default policy version will be set to 2 if this variable is omitted. Change-Id: I62a29c1bef36c259ec4b11259f71be613d20a112
