Setting sc->swappiness to zero will make the reclaimer hit unmapped pages until we get into problems. Maybe set that to some negative value to avoid reclaim_mapped being set to 1 in shrink_active_list? Oh. But reclaim_mapped is staying at zero anyways if may_swap is off. So we are already fine. I still wonder why you are doing this at all. If you just run your own app on the box then preallocate your higher order allocations from user space. Much less trouble. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
