It's unclear (to me) which tree would normally carry these.

But there are significant textual conflicts with the "Per-VMA locks"
patchset, and there might be functional issues as well.  So mm.git
would be the better choice.

Please can you redo and retest against tomorrow's mm-unstable branch
(git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm)?  Hopefully the
sched developers can take a look and provide feedback.

Thanks.
