Hi all, I ran the latest blktests (git hash: b35866f2d0df) with v6.1 kernel and observed 5 test cases fail. I call for support to fix them. List of failure cases ===================== #1: block/011 #2: block/024 #3: nvme/002 #4: nvme/016 #5: nvme/017 Failure description =================== #1: block/011 The test case fails with NVME devices due to lockdep WARNING "possible circular locking dependency detected". Reported in September [1] and solution was discussed. A kernel fix patch was posted [2]. It may not be the best fix.

Need further investigation. #2: block/024 Fails on slow machines. I suspect test case needs improvement.
