Subject: mmotm git tree since-4.9 branch created (was: mmotm 2016-12-12-17-02
uploaded)
I have just created since-4.9 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.9 tag in Linus tree and mmotm-2016-12-12-17-02.
Tracking all the dax related changes was quite challenging but I hope I
have it all. I have pulled from
- Dave's tree: dax-4.10-iomap-pmd, xfs-4.10-misc-fixes-2,
iomap-4.10-directio
- Ted's tree: dev
- Dan's tree: libnvdimm-for-next
Let me know if I am missing anything, please.
As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
