Unfortunately we cannot get rid of the sha1 code yet (lib/sha1.o is built-in unconditionally), as there are other users...kernel/bpf/core.c and net/ipv6/addrconf.c Could they be switched to blake2s, too?
I've brought this up before and the conclusion is that they probably can't for compatibility reasons. No need to rehash that discussion again. Alternatively, send a patch to netdev and see how it goes. Anyway, we can follow up with the code size reduction patches we discussed elsewhere in this thread.
