Still no independent confirmation as to whether this is a problem or not.
I think it is, so I'll propose this patchset to fix it. Patch 1/3 has a
reasonable description of the problem.

Thanks,
Nick

Updated some comments, added diffstats to patches, don't use __SetPageUptodate
as an internal page-flags.h private function.

I would like to eventually get an ack from Hugh regarding the anon memory
and especially swap side of the equation, and a glance from whoever put the
smp_wmb()s into the copy functions (Was it Ben H or Anton maybe?)

Thanks,
Nick
