So, we fixed it, but we don't know why.
Peter Xu's patchset that fixed it is here: https://lore.kernel.org/lkml/20200821234958.7896-1-peterx@redhat.com/
Yeah, that's the part that ends up being really painful to backport (with all the subsequent fixes too), so the 4.14 people would prefer to avoid it.
But I think that if it's a "requires dax pmem and ptrace on top", it may simply be a non-issue for those users. Although who knows - maybe that ends up being a real issue on Android..
A lot to digest, so I need to do some reading now. Thanks everyone!
