Subject: Re: mmotm 2015-04-23-16-38 uploaded

I have just created since-4.0 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.0 tag in Linus tree and mmotm-2015-04-23-16-38.

I have pulled some cgroup wide changes from Tejun.

As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
