Subject: Shared mmap'ed page writeback 2.6.18 backport

Hi,

Has anyone backported the recent shared mmap page writeback fix 
(7658cc289288b8ae7dd2c2224549a048431222b3) to 2.6.18 or previous?

It looks like there will be at least one more 2.6.18-stable release and 
I'd like to see it fixed there.

I don't know enough about the VM layer to understand this further, but 
the real "problem" in simply backporting the patch seems to be in this part:

+		if (page_mkclean(page))
+			set_page_dirty(page);

page_mkclean did not exist in 2.6.18. Is there a simple solution or 
should backporting the commit with added page_mkclean 
(d08b3851da41d0ee60851f2c75b118e1f7a5fc89) be considered instead? 
Hopefully that one has no other dependencies...

Thanks!
Daniel
