I've been running most of my tests on a GCE VVM (using gce-xfstests) with a 100GB PD-SSD as the storage device. I just tried, and it's passing now reliably on both 4k and 1k for me, both on v5.11 and v5.12-rc1. (Previously it was failing about 30% of the time on the ext4/1k test scenario, and was passing 100% on ext4/4k.) Given your report, I tried running it using KVM (with a NVME ssd as the back-end storage device), and it's failing 80% of the time using the 4k block size. So previously I had assumed that it was passing consistently on with ext4/4k, but it looks like that it's very much dependent on the performance of the TEST_DEV. - Ted
