Hi all, I ran the latest blktests (git hash: f79783b44a5b) with the v6.10 kernel. Also I checked the CKI project run results. In total, four failures were observed, as listed below. The nvme/050 failure observed with the kernel v6.10-rc1 [1] was fixed and no longer observed. Good.

The failure cause was the race between nbd-server port readiness and nbd-client connect. A fix patch for blktests is posted [6].
