Linus Torvalds 8129bac60f fscrypt updates for 6.2
This release adds SM4 encryption support, contributed by Tianjia Zhang.
 SM4 is a Chinese block cipher that is an alternative to AES.
 
 I recommend against using SM4, but (according to Tianjia) some people
 are being required to use it.  Since SM4 has been turning up in many
 other places (crypto API, wireless, TLS, OpenSSL, ARMv8 CPUs, etc.), it
 hasn't been very controversial, and some people have to use it, I don't
 think it would be fair for me to reject this optional feature.
 
 Besides the above, there are a couple cleanups.
