Hi Christoph, We reported "[axboe-block/for-6.3/block] [blk] 84d7d462b1: mdadm-selftests.03assem-incr.fail" at https://lore.kernel.org/all/202302060916.19871c31-yujie.liu@intel.com/ We noticed this commit has been merged to linux-next, and we caught several failed mdadm tests on it, while its parent commit is clean, so we report again FYI and Cc linux-raid, thanks. ========================================================================================= tbox_group/testcase/rootfs/kconfig/compiler/disk: lkp-hsw-d05/mdadm-selftests/debian-11.1-x86_64-20220510.cgz/x86_64-rhel-8.3-func/gcc-11/1HDD commit: 180b04d450a71 ("blk-cgroup: remove the !bdi->dev check in blkg_dev_name") 84d7d462b16dd ("blk-cgroup: pin the gendisk in struct blkcg_gq") 180b04d450a71372 84d7d462b16dd5f0bf7c7ca9254 ---------------- --------------------------- fail:runs %reproduction fail:runs | | | :6 100% 6:6 mdadm-selftests.03assem-incr.fail :6 100% 6:6 mdadm-selftests.03r5assem-failed.fail :6 100% 6:6 mdadm-selftests.04r1update.fail :6 100% 6:6 mdadm-selftests.04update-uuid.fail :6 33% 2:2 mdadm-selftests.06name.fail :6 33% 2:2 mdadm-selftests.06wrmostly.fail :6 33% 2:2 mdadm-selftests.02r1add.fail :6 33% 2:2 mdadm-selftests.02r1grow.fail :6 33% 2:2 mdadm-selftests.02r5grow.fail :6 33% 2:2 mdadm-selftests.02r6grow.fail commit: 84d7d462b16dd5f0bf7c7ca9254bf81db2c952a2 ("blk-cgroup: pin the gendisk in struct blkcg_gq") https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master in testcase: mdadm-selftests version: mdadm-selftests-x86_64-5f41845-1_20220826 disk: 1HDD test_prefix: 03 on test machine: 8 threads 1 sockets Intel(R) Core(TM) i7-4790T CPU @ 2.70GHz (Haswell) with 16G memory caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace): [ 128.373618][ T1704] loop0: detected capacity change from 0 to 40000 [ 128.571618][ T1713] loop1: detected capacity change from 0 to 40000 [ 128.767468][ T1718] loop2: detected capacity change from 0 to 40000 [ 128.965651][ T1723] loop3: detected capacity change from 0 to 40000 [ 129.163065][ T1728] loop4: detected capacity change from 0 to 40000 [ 129.366600][ T1733] loop5: detected capacity change from 0 to 40000 [ 129.566630][ T1741] loop6: detected capacity change from 0 to 40000 [ 129.764382][ T1746] loop7: detected capacity change from 0 to 40000 [ 130.326896][ T1751] loop8: detected capacity change from 0 to 131072 [ 130.898545][ T1759] loop9: detected capacity change from 0 to 131072 [ 131.469675][ T1764] loop10: detected capacity change from 0 to 131072 [ 132.038384][ T1772] loop11: detected capacity change from 0 to 131072 [ 132.603489][ T1780] loop12: detected capacity change from 0 to 131072 [ 133.173539][ T1785] loop13: detected capacity change from 0 to 131072 [ 133.192944][ T282] Testing on linux-6.2.0-rc6-00077-g84d7d462b16d kernel [ 133.192955][ T282] [ 133.537132][ T282] /lkp/benchmarks/mdadm-selftests/tests/03r5assem-failed...
