Hi Damien, If 'qd=1' is changed into 'qd=2' in tests/zbd/012 then this test fails against all kernel versions I tried, including kernel version 6.9. Do you agree that this test should pass? If you agree with this, do you agree that the only solution is to postpone error handling of zoned writes until all pending zoned writes have completed and only to resubmit failed writes after all pending writes have completed? Thanks, Bart.
