From f486135ebab4fb91366a1e41fb15ed3036ad0cf9 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 15 Mar 2017 16:17:03 +0100 Subject: [PATCH] btrfs: remove unused qgroup members from btrfs_trans_handle The members have been effectively unused since "Btrfs: rework qgroup accounting" (fcebe4562dec83b3), there's no substitute for assert_qgroups_uptodate so it's removed as well.
