Remind me what your fstests git repo is again? The generic/750 test in my patch 2/2 that I sent out reproduces the problem super-reliably, so long as fsstress actually issues the io_uring reads and writes. So if you have your patch applied which suppresses io_uring from fstress by default, you might need to modify the patch series to force the io_uring, at which point it quite nicely demonstrates the fsstress ; umount problem. (It sometimes requires more rounds of fsstress ; umounts before it repro's on the xfs/4k, but it repro's really nicely on ext4/4k). xfs/4k: generic/750 Failed 3s generic/750 Failed 1s generic/750 Failed 33s generic/750 Failed 1s generic/750 Pass 33s ext4/4k: generic/750 Failed 3s generic/750 Failed 2s generic/750 Failed 7s generic/750 Failed 2s generic/750 Failed 7s - Ted
