Subject: Shared mmap'ed page writeback 2.6.18 backport
Date: Wed, 03 Jan 2007 17:03:18 -0500	[thread overview]
Message-ID: <459C2826.8040602@gentoo.org> (raw)

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
