This is motivated by a bug in btrfs where the number of blocks used does not change. It currenly fails on btrfs and it is fixed by a patch that has the following subject: "btrfs: fix missing delalloc new bit for new delalloc ranges" Signed-off-by: Filipe Manana Reviewed-by: Josef Bacik --- tests/generic/614 | 50 +++++++++++++++++++++++++++++++++++++++++++ tests/generic/614.out | 2 ++ tests/generic/group | 1 + 3 files changed, 53 insertions(+) create mode 100755 tests/generic/614 create mode 100644 tests/generic/614.out diff --git a/tests/generic/614 b/tests/generic/614 new file mode 100755 index 00000000..80edf9cd --- /dev/null +++ b/tests/generic/614 @@ -0,0 +1,50 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2020 SUSE Linux Products GmbH.
