Actually, the first allocation loop in __alloc_pages() is testing against zone->pages_high and allocating only from zones which have MORE than this. So I guess this should only result in a somewhat slower and/or softer fallback and definately worth a try. Oh, and we definately need to un-lazy the queue movement from the inactive_clean list. Having all of the pages you counted on as being reclaimable referenced is a very bad surprise ... regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to lose... http://www.surriel.com/ http://distro.conectiva.com/ Send all your spam to aardvark@nl.linux.org (spam digging piggy) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
