Subject: since-3.18 branch opened for mm git tree (was: Re: mmotm 2014-12-15-17-05 uploaded) I have just created since-3.18 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v3.18 tag in Linus tree and mmotm-2014-12-15-17-05. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347) The current shortlog says: Akinobu Mita (1): cma: make default CMA area size zero for
