I didn't look at zswap. At first glance, when zswap fallbacks to writeback, it
will make swap very sparse (so cause bad IO pattern), since some pages are
compressed, some not. Is this the problem you are trying to solve? This should
exist without my patch too. Sorry, I have no idea. I'm afraid zswap need manage
the swap partion by itself.
Thanks,
Shaohua
