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.

Thanks, this is really frustrating, still very grateful for your advice
and review.
Best regards,
