Sorry for followup on my own mail, but there is another thing that comes to my mind:
swap_out is currently in no way priority-dependant. But it could be (the parameter is there). How about swapping more pages in tighter memory situation? The basic idea is that if there is a rising need for mem it cannot be wrong to do a bit more than under normal circumstances. One could achieve this simply by:
int counter, nr_pages = SWAP_CLUSTER_MAX; to int counter, nr_pages = SWAP_CLUSTER_MAX * DEF_PRIORITY / priority; in swap_out. The idea behind is to reduce the overhead in finding out if swapping is needed by simply swapping more everytime we already gone "the long way to knowing".
