From d28fc3dbe1918333730d62aa5f0d84b6fb4e7254 Mon Sep 17 00:00:00 2001 From: Nick Terrell Date: Fri, 30 Mar 2018 12:14:53 -0700 Subject: crypto: zstd - Add zstd support Adds zstd support to crypto and scompress. Only supports the default level. Previously we held off on this patch, since there weren't any users. Now zram is ready for zstd support, but depends on CONFIG_CRYPTO_ZSTD, which isn't defined until this patch is in. I also see a patch adding zstd to pstore [0], which depends on crypto zstd.
