The reclaimer is passed a control structure that can be used to disable write to swap (if that is the concern).

The traditional reclaim works fine if told what to do. Introducing another LRU list to do reclaim is a significant change to the VM, creates lots of overhead etc. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
