I believe this patch is the right way to go for low-mem situations.
It also might alleviate some fragmentation problems, since (in
2.1.89) some folks got swap-deaths in which 80% of memory was
freed but no two contiguous large areas could be found. The only
conclusion is that there still were some 'unswappable' things
left. With your patch the number of unswappable things is reduced
and thereby the number of fragmentation problems should also become
less.
Linus, this patch looks good and 'obviously correct' to me; maybe
you should consider integrating it when the balancing issues wrt.
this patch are done?
Rik.
