Hello CKI reported most of the blktests nvme/tcp tests failed on the linux tree[1], here is the reproducer and dmesg log, the issue cannot be reproduced with 6.11.0, seems it was introduced with the latest block code merge, please help check it and let me know if you need any info/testing about it, thanks.
