FWIW there is also a pure -mm (non-rebased) git tree at http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary since-3.6 branch. It is based on top of 3.6 with mm patches from Andrew's tree. HTH -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
