[PATCH v3 1/2] crypto: use SM3 instead of SM3_256
From: Tianjia Zhang <hidden>
Date: 2021-10-26 07:56:34

Herbert Xu, "David S. Miller", James Bottomley, Jarkko Sakkinen, Mimi Zohar, David Howells, Paul Moore, James Morris, "Serge E. Hallyn", Linus Torvalds, Peter Huewe
According to https://tools.ietf.org/id/draft-oscca-cfrg-sm3-01.html, SM3 always produces a 256-bit hash value and there are no plans for other length development, so there is no ambiguity in the name of sm3.
