Subject: since-3.19 branch opened for mm git tree (was: Re: mmotm
 2015-02-25-21-19 uploaded)

I have just created since-3.19 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v3.19 tag in Linus tree and mmotm-2015-02-25-21-19.

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)
