Hi,
I have just pushed a new since-3.7 branch to the -mm git tree
(git://git.kernel.org/.../mhocko/mm.git) which is tagged as
mmotm-2012-12-14-17-51.
This branch contains all -mm related patches on top of v3.7 Linus tree.
The following branches have been merged into the tree:
- for-3.8 -git://git.kernel.org/.../tj/cgroup.git
- slab/next - git://git.kernel.org/.../penberg/linux.git
- balancenuma-v11 - git://git.kernel.org/.../mel/linux-balancenuma
If there are any other that are needed for -mm, just let me know. If
there are any branches which will continue in development and they have
conflicts potential (e.g. cgroup with memcg work or slab with kmem
accounting) then let me know and I will set up them for periodic merging
(which expects that those branches are pre merge window like in the
past).
