does 2.6 kernel still have the clean list?

as in 2.4 kernel, there was a clean list in address_space struct, but now we cannot find it, radix-tree now is used for list, but does not specify the clean list, I find the page will be deleted from the radix tree after being writen to the disk. won't it still be in a clean list for some time for better performance?

I'm not up on this at all accept yes they no longer use address_space in the page cache.
Seems like page cache is for when there is a not page then fetch it out of cache.
and by definition isn't a not current page a clean page ?
a dirty page can't be in the cache can it ?

Thx for your reply.

What my consideration is the swapper(swapper_space).
When a page is writen to the disk, won't it be in cache for some time ? When page fault happens, we might get the page from the cache, while need not to read the disk.
