Re: kswapd @ 60-80% CPU during heavy HD i/o.

BTW, what loop are you trying to "continue;" out of here?

+			    do {
 				if (tsk->need_resched)
 					schedule();
 				if ((!zone->size) || (!zone->zone_wake_kswapd))
 					continue;
 				do_try_to_free_pages(GFP_KSWAPD, zone);
+			   } while (zone->free_pages < zone->pages_low &&
+					   --count);

:-)  Just add a "next_zone:" label at the end of that code and
change the continue; to a goto next_zone;
