Subject: Re: [patch] mm, mempolicy: Introduce spinlock to read shared policy tree

Ok, this looks fine to me, but I'd like to get a sign-off from Kosaki
too, and I guess it's really not all that urgent, so I can do the -rc1
release tonight without worrying about it, knowing that a fix is at
least pending, and that nobody is likely to actually ever hit the
problem in practice anyway.
