Signed-off-by: Zorro Lang --- Hi, In V1 patch[1], Darrick pointed out that it's not suit for covering e001873853d8 ("xfs: ensure we capture IO errors correctly"). So I changed this case to be an ordinary xfs buf_ioerror test. How about this method? Thanks, Zorro [1] https://lore.kernel.org/fstests/20221027022459.5ewhsm7gjq5iynra@zlang-mailbox/T/#m856a77c4bb5a61191afeb378b1178f1691ffb8f8 tests/xfs/554 | 49 +++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/554.out | 4 ++++ 2 files changed, 53 insertions(+) create mode 100755 tests/xfs/554 create mode 100644 tests/xfs/554.out diff --git a/tests/xfs/554 b/tests/xfs/554 new file mode 100755 index 00000000..1135f4f3 --- /dev/null +++ b/tests/xfs/554 @@ -0,0 +1,49 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (c) 2022 Red Hat, Inc.
