That last one needs to be dropped--see my note about why in [1].
And syzbot is also complaining [2], correctly, that you can't pass
FOLL_LONGTERM to pin_user_pages_locked().

And the patch right before it, while correct as it stands, should end
up being unnecessary, because Daniel is taking a different approach.

So probably best to drop both of those from mmotm and -next.
