SM4 is widely used in China's data encryption software and hardware.
This serial of patches enables the SM4-XTS algorithm in blk-crypto and
enables the SM4-XTS/CTS algorithm in fscrypt to encrypt file content
and filename.

v2 change:
  - As Eric said, the new FSCRYPT_MODE is defined for the unused numbers 7 and 8

Tianjia Zhang (2):
  blk-crypto: Add support for SM4-XTS blk crypto mode
  fscrypt: Add SM4 XTS/CTS symmetric algorithm support
