I have just created since-4.1 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.1 tag in Linus tree and mmotm-2015-07-06-16-25.
I have pulled block/core changes as a pre-requisite for Tejun's cgroup
writeback series which is applied on top (I have cherry picked those
because merging it would pull in way too many changes). I have also
pulled cgroup core changes. I hope I haven't forgotten anything.
As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
The shortlog says:
