SM4 is widely used in China's data encryption software and hardware.
these algoritms are mandatory in many scenarios. 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.

v4 changes:
  - only allow the SM4 XTS/CTS algorithm in policy v2 for fscrypt
  - update git commit message

v3 change:
  - update git commit message

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

  blk-crypto: Add support for SM4-XTS blk crypto mode
  fscrypt: Add SM4 XTS/CTS symmetric algorithm support

Applied.  I don't think anyone should actually use this, but with the SM*
algorithms turning up everywhere these days, and people seemingly being totally
okay with that for some reason, I don't think it's fair for me to reject this.
