mmotm git tree since-4.3 branch created (was: Re: mmotm 2015-11-10-15-53 uploaded)
From: Michal Hocko
Date: Wed Nov 11 2015 - 07:23:39 EST
I have just created since-4.3 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.3 tag in Linus tree and mmotm-mmotm-2015-11-10-15-53.
As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
