Hi Luigi,
It's another patch without dependency with previous my patches.
You can control /proc/sys/vm/swappiness up to 200(which means VM reclaimer
can reclaim only anonymous pages) so I hope it makes swap device full while
file-backed page(ie, code pages) are protected from eviction.
I hope this patch removes your hacky min_filelist_kbytes.
Could you try this and send feedback?
