Hi all, I ran the latest blktests (git hash: 80430afc5589) with the v6.11 kernel. This time, failures reported by the CKI project are not included in this report, since blktests run by the CKI project for the mainline kernel looks stopping since August. Comparing with the previous report using the v6.11-rc1 kernel [1], two failures were addressed. The srp/002 failure was fixed on the kernel side, and the nvme/052 failure was fixed on the blktests side. [1] https://lore.kernel.org/linux-block/5yal5unzvisrvfhhvsqrsqgu4tfbjp2fsrnbuyxioaxjgbojsi@o2arvhebzes3/ List of failures ================ #1: nvme/014 (tcp transport) #2: nvme/041 (fc transport) #3: scsi/008 Failure description =================== #1: nvme/014 (tcp transport) With the trtype=tcp configuration, nvme/014 fails occasionally with the kernel message "DEBUG_LOCKS_WARN_ON(lock->magic != lock)". It is rare, and 200 times of repeat is required to recreate the failure. A fix patch candidate was posted [2].
