I love the Linux community, because this memory shortage has prompted two quite significant developments. Firstly, quite a substantial speedup of the Zram/Zswap (whichever one it is) systems (and a little improvement on compression), secondly, a potentially whole new memory compression stack referred to as CRAM that could allow reading compressed memory directly at near-DRAM speeds.

While making current memory management more efficient won't in any case effectively solve the memory shortage, as none of these savings are comparable to effectively giving you a free extra stick, it is awesome that people have spent significant effort on this front.
