Subject: [GIT PULL] Cgroup writeback support for 4.2
Hi Linus,
This is the big pull request for adding cgroup writeback support. This
code has been in development for a long time, and it has been simmering
in for-next for a good chunk of this cycle too. This is one of those
problems that has been talked about for at least half a decade, finally
there's a solution and code to go with it.
Also see last weeks writeup on LWN:
http://lwn.net/Articles/648292/
This pull request is on top of for-4.2/core, sent out earlier.
Please pull!
