As part of the ongoing efforts to sub-divide memory management
maintainership and reviewership, establish a section for Kernel Samepage
Merging (KSM) and add appropriate maintainers and reviewers.
Signed-off-by: Lorenzo Stoakes <lorenzo.stoakes@oracle.com>

REVIEWERS NOTES:
I took a look through git blame, past commits, etc. and came up with what
seems to be a reasonable list of people here, if you don't feel you ought
to be here, or if you feel anybody is missing (including yourself!) let me
know :)
David has kindly already agreed to be co-maintainer for this section.

I guess my point is, as a submitter you expect that people that are listed under R: that you are supposed to CC would actually ... review? :D In that case, I would prefer to have actual reviewers there. If there are none, then there should be none listed. Of course, If Xu and Chengming do *want* to actively review KSM code changes, I would be more than happy to list them. -- Cheers, David / dhildenb

Sure, so I think best thing is to ask: Xu, Chengming - do you WANT to be reviewers here? :) if not, happy to drop. I could add myself as a reviewer as a backup option in case you need review also guys, though KSM is really not my area but I can approach from first principles at least.

Sure, I am more than willing to take on the role of reviewer for the KSM module. I am pleasured to dedicating my time to reviewing new patches about KSM on the mailing list.
