Hmm, very interesting. This time the pte present bit is set, so the page is really there. The pte flags say dirty/user/rw/present, and the vma flags say shared/write/read. Looks like it really shouldn't be swap-cached.
So the writable swap-cache problem appears to be back in a different form. Can you reproduce this easily? We need to figure out what sequence of events leads up to this ...
