I would have expected to see some numbers, however I guess the "merge unless proven bad" approach for new features works too. I had a quick look at the code, and I think it still needs more cleanup and review... it is vaguely difficult to participate in discussions about these patches because they are often split over several iterations of versions/fixes, and because it isn't always clear what they depend on (although in the case of swap prefetching, that isn't so much of a problem). And also, there is no linux-mm thread to reply to... could we have some of the intrusive mm/ patches intended for 2.6.18 posted here before they get merged, or is that too much trouble? As far as swap prefetching itself goes, I still don't like it much (same issues still stand), but with some cleaning up the patch shouldn't be too bad, and I can turn it off... so if people want it and if numbers show it is working, I wouldn't object. -- SUSE Labs, Novell Inc.
