Are you sure that the backport is complete? I do not see binder code to be patched, nor khugepaged. Have you considered all places that take the exclusive mmap_sem on a remote process mm? See my backport for 4.4 stable tree http://lkml.kernel.org/r/20190604094953.26688-1-mhocko@kernel.org for reference. Also please note that my backport needs to be reviewed as well.
