Hi all, I ran the latest blktests (git hash: 25efe2a1948d) with the v6.11-rc1 kernel. Also I checked the CKI project run results with the kernel. In total, I observed three failures as listed below. Comparing with the previous report using the v6.10 kernel [1], two failures of dm/002 and nbd/001,002 were addressed by blktests side fixes. The srp/002 failure with v6.10 kernel was addressed by the kernel side fix (Thanks!). However, srp/002 had another new failure symptom with v6.11-rc1 kernel.
