I suspect we won't be needing that code. The SEQ replacement for swap backed pages might reduce the number of pages that need to be scanned to a reasonable number. Remember, steady states are not a big problem with the current VM. It's the sudden burst of scanning that happens when the VM decides that it should start swapping (and every anonymous page is referenced) that kills large systems. -- All Rights Reversed -- 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/
