However, it is a sure thing that desktop users and smartphone
users do want an earlier OOM kill.
I wonder if doing an OOM kill when the number of free pages
plus the number of file lru pages in every zone is below
pages_high and there is no more swap available might work?
On the other hand, that still leaves us cgroups. What could
be appropriate there?
