We were planning on suggesting that such users set swappiness=0 to give
user pages priority over the page cache pages. But it doesn't look like that works very well in the more recent kernels.
One (perhaps) desirable feature would be for intermediate values of swappiness to have behavior in between the two extremes (mapped pages have higher priority vs page cache pages having priority over unreferenced mapped pages),
so that one would have finer grain control over the amount of swap used. I'm not sure how to achieve such a goal, however. :-)
Priority paging again? A perennial suggestion.

I wonder if this is because I just posted it to linux-mm or its not fleshed out enough yet to be interesting?
It was very noncontroversial. Since it's apparently useful to someone
and generally low-impact it should probably be merged.
