Well I just got all the "hard" core mm stuff past Linus in this merge
window, and got a couple of preexisting memory ordering bugs fixed..
So I am planning to get it into -mm, ready for the next merge window.
I'm a little concerned about Peter's instability reports, but maybe
they're just an -rt thing. But I don't think we've found any holes in
fast_gup yet (although I think I need to add one last check to ensure
it won't pick up kernel addresses).
Thanks,
Nick
