From 9ebfc111a1e34fcec5285095954c360acc2be01a Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Tue, 26 Jul 2022 23:11:24 +0300 Subject: tests-bdrv-drain: bdrv_replace_test driver: declare supports_backing We do add COW child to the node. In future we are going to forbid adding COW child to the node that doesn't support backing. So, fix it here now. Don't worry about setting bs->backing itself: in further commit we'll update the block-layer to automatically set/unset this field in generic code.
