This set of patches was awesome but also pretty large and touched some nontrivial parts, so it's not just a simple matter of merging them wholesale. I merged a handful of these patches to my own private 3.14.x tree where they work wonderfully, and some have already appeared in the latest stable-3.14.21. Greg also said that he has more in the queue. :) The one I have so far punted on due to the filesystem dependencies is 2457aec63745e235bcafb7ef312b182d8682f0fc aka: "mm: non-atomically mark page accessed during page cache allocation where possible" - that would be really nice to have. -h
