Excuse me, I can't find these patches in: git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git git://git.cmpxchg.org/linux-mmots.git Could you point at the tree which I can rebase onto? Should I cherry-pick Quentin's patches manually? Best regards, Alexander
