Have you noticed that pool_pages >> stored_pages, like this:
[root@ca-dev32 zswap]# cat *
0
424057
99538
0
2749448
0
24
60018
16837
[root@ca-dev32 zswap]# cat pool_pages
97372
[root@ca-dev32 zswap]# cat stored_pages
53701
[root@ca-dev32 zswap]#

I think it's unreasonable to use more pool pages than stored pages!

Regards,
-Bob
