From bf38be65f3703d5ef3661c0a2802bc28e76b8f19 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 23 Oct 2019 18:48:11 +0200 Subject: btrfs: move block_group_item::used to block group For unknown reasons, the member 'used' in the block group struct is stored in the b-tree item and accessed everywhere using the special accessor helper. Let's unify it and make it a regular member and only update the item before writing it to the tree. The item is still being used for flags and chunk_objectid, there's some duplication until the item is removed in following patches.
