[PATCH] driver: zram: fix wrong counting on pages_store
From: Huangzhaoyang
Date: Tue Jul 20 2021 - 02:50:13 EST
From: Zhaoyang Huang <zhaoyang.huang@xxxxxxxxxx>
It makes the statistic confused when counting pages_store in during writeback.
pages_store should just reflect the swapped pages on ZRAM, while bd_writes be
responsible for writeback things.
