I've looked, and it doesn't yet, but Rik has already marked the places
where this would be implemented and it looks simple (famous last
words): mark the swap cache page dirty at writeout and flush to disk
during refill_inactive. Rik is sitting a few rows behind me right now
so we'll look at the code later today. He's already been talking
about doing this anyway to improve the write clustering of the swapout
code.
