FYI, I tried to recreate this failure on my test system this week, and found it is no longer recreated. In case your TODO list includes a work item for this issue, please put lower priority on it. Two month ago, the failure had been recreated by repeating the blktests test cases nvme/030 and nvme/031 with SIW tranposrt around 30 times. Now I do not see it when I repeat them 100 times. I suspected some kernel changes between v6.4 and v6.5 would have fixed the issue, but even when I use both kernel versions, the failure is no longer seen. I reverted nvme-cli and libnvme to older version, but still do not see the failure. I just guess some change on my test system affected the symptom (Fedora 38 on QEMU).
