I haven't been able to reproduce this -- both with and without my patch on mm-new and mainline; I see why you've commented out uffd-tests in your test script :) I ran into this *once* earlier when liburing wasn't installed, perhaps that could be related? Will send a v5 soon retaining the test_uffdio_copy_eexist variable as suggested. Thanks, Ujwal
