From ca4ac360af94964906149efe166453ac83ae7c43 Mon Sep 17 00:00:00 2001 From: Dennis Zhou Date: Mon, 4 Feb 2019 15:19:59 -0500 Subject: btrfs: manage heuristic workspace as index 0 While the heuristic workspaces aren't really compression workspaces, they use the same interface for managing them. So rather than branching, let's just handle them once again as the index 0 compression type.
