It seems your patch is better than mine. Thanks. :) But my concern is that as Peter pointed out, unevictable lru's solution is not fundamental one. He want to remove ramfs page from lru list to begin with. I guess Andrew also thought same thing with Peter. I think it's a fundamental solution. but it may be long term solution. This patch can solve NOMMU problem in current status. Andrew, What do you think about it ?
