I rewrote patches to create new zone as ZONE_EASY_RECLAIM. Probably, many guys of here remember the discussion about Mel-san's "fragmentation avoidance" patch in the last week. In the discussion, another way was creating new zone like these patch which I posted one years ago. http://sourceforge.net/mailarchive/forum.php?thread_id=5969508&forum_id=223 My motivation of creating new zone was for memory hotplug. (Previous name of the zone was ZONE_REMOVABLE.) It aimed to collect the page which was difficult for removing on few nodes, and it made other nodes this zone to be removed easier. But, I thought Mell-san's patch is also useful for this purpose. So, I stopped my work about it after his patch was introduced. Howerver unfortunately, Linus-san didn't agree his patches at last week. So, I felt my old work should be restarted. Frankly, I don't see that my patch set is/will be the best way for others. My patch didn't concern about fragmentation. And this patch has pros and cons as Mel-san said. But I realize each persons are expecting against new zone for each reason. So, I changed the name of new zone as ZONE_EASY_RECLAIM. I wish this become good start point for them to be able to be happy. This patch is for 2.6.14. Please comment.
