Cover letter [PATCH v4 0/7] zram idle page writeback
Inherently, swap device has many idle pages which are rare touched since it was allocated. It is never problem if we use storage device as swap. However, it's just waste for zram-swap.
This patchset supports zram idle page writeback feature.
* Admin can define what is idle page "no access since X time ago"
