Thanks for sharing this, I was able to reproduce and fix the problem. Turns out char *area_src_alias, area_dst_alias, area_remap were left uninitialized in uffd_test_ctx_init while it was working before this refactor because of the global nature of these variables. Using virtme-ng also helps me ensure that the next spin on this patch will work :) > Ideally the test changes > should run the same before/after that series applied. Meanwhile, no > conflict expected between the two, hence no worry on the order to land. Sorry, I meant to link the uffd_poison_test changes [1], I've rebased on top of those changes. Will send a v6 soon. [1] https://lore.kernel.org/all/20250620150058.1729489-1-pet...@redhat.com/ Thanks, Ujwal
