I have just created since-4.2 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v4.2 tag in Linus tree and mmotm-2015-09-10-16-30. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347) The shortlog says: Aleksa Sarai (4): cgroup: allow a cgroup subsystem to reject a fork
