This test is motivated by a recent regression introduced in the linux kernel's 4.18 merge window and is fixed by a patch with the title: "Btrfs: fix mount failure when qgroup rescan is in progress" Signed-off-by: Filipe Manana --- tests/btrfs/166 | 57 +++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/166.out | 2 ++ tests/btrfs/group | 1 + 3 files changed, 60 insertions(+) create mode 100755 tests/btrfs/166 create mode 100644 tests/btrfs/166.out diff --git a/tests/btrfs/166 b/tests/btrfs/166 new file mode 100755 index 00000000..c74b0861 --- /dev/null +++ b/tests/btrfs/166 @@ -0,0 +1,57 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2018 SUSE Linux Products GmbH.
