I just got time to have a closer look on the uffd-wp triggering of the warning here: https://lore.kernel.org/all/YzeR+R6b4bwBlBHh@x1n/T/#u It turns out to be a wrong check on vma, and with the fix attached we should be able to remove the ugly macro checks. Sorry for the bothersome. Please have a look, thanks.
