I posted the fix for this one yesterday (found while doing more code
reviews of the upstream code searching for any other potential issue):

https://www.spinics.net/lists/linux-mm/msg122905.html
https://www.spinics.net/lists/linux-mm/msg122903.html

Could you test with those two applied on top of the others updates
that are already in -mm?

Thanks!
Andrea
