Some (related) topics proposed for the MM track:

1) Optimizing the utilization of RAM as a resource, i.e. how do we teach the
    kernel to NOT use all RAM when it doesn't really "need" it.  See
    http://lwn.net/Articles/475681/ (or if you don't want to read the whole
    article, start with "Interestingly, ..." four paragraphs from the end).

2) RAMster now exists and works... where are the holes and what next?

3) Next steps in the page replacement algorithm:
	a) WasActive https://lkml.org/lkml/2012/1/25/300
	b) readahead http://marc.info/?l=linux-scsi&m=132750980203130

4) Remaining impediments for merging frontswap

5) Page flags and 64-bit-only... what are the tradeoffs?
I am interested in these topics.
