Hi,
there are two issues this patch series attempts to fix. First one is
something that has been broken since MMF_UNSTABLE flag introduction
and I guess we should backport it stable trees (patch 1). The other
issue has been brought up by Wenwei Tao and Tetsuo Handa has created
a test case to trigger it very reliably. I am not yet sure this is a
stable material because the test case is rather artificial. If there is
a demand for the stable backport I will prepare it, of course, though.

I hope I've done the second patch correctly but I would definitely
appreciate some more eyes on it. Hence CCing Andrea and Kirill. My
previous attempt with some more context was posted here
http://lkml.kernel.org/r/20170803135902.31977-1-mhocko@kernel.org

My testing didn't show anything unusual with these two applied on top of
the mmotm tree.
