From f9e8456c39136aa41f85f82758a00e5aa2aab334 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Thu, 16 Aug 2018 12:33:13 +0200 Subject: [PATCH] radv: initialize the DCC predicate correctly when it's compressed We have to do a fast-clear eliminate when clearing DCC metadata with 0x20202020. I don't know if that fixes anything but that seems correct to me.
