This test is motivated by an issue in btrfs where this scenario triggered a warning (without any side effects). The following linux kernel patch fixes the issue in btrfs: "Btrfs: fix warning when replaying log after fsync of a tmpfile" Signed-off-by: Filipe Manana --- tests/generic/506 | 58 +++++++++++++++++++++++++++++++++++++++++++++++++++ tests/generic/506.out | 3 +++ tests/generic/group | 1 + 3 files changed, 62 insertions(+) create mode 100755 tests/generic/506 create mode 100644 tests/generic/506.out diff --git a/tests/generic/506 b/tests/generic/506 new file mode 100755 index 00000000..7d28d3b0 --- /dev/null +++ b/tests/generic/506 @@ -0,0 +1,58 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2018 SUSE Linux Products GmbH.
