They reproduced the flaw, using Paul Eggert's reproducer with futimens added, on kernel 4.18.0-80.11.2.el8_0.x86_64 and I'm suffering it on 4.18.0-147.3.1.el8_1.x86_64. The copy ran correctly on 5.6.0-0.rc0.git5.1.fc32.x86_64. I've asked twice that the bug, https://bugzilla.redhat.com/show_bug.cgi?id=1803162, be made publicly accessible.
