@ -70,9 +70,7 @@ e.g. ``zswap.zpool=zbud``. It can also be changed at runtime using the sysfs
The zbud type zpool allocates exactly 1 page to store 2 compressed pages, which
means the compression ratio will always be 2:1 or worse (because of half-full
zbud pages). The zsmalloc type zpool has a more complex compressed page
storage method, and it can achieve greater storage densities. However,
zsmalloc does not implement compressed page eviction, so once zswap fills it
cannot evict the oldest page, it can only reject new pages.
storage method, and it can achieve greater storage densities.
When a swap page is passed from frontswap to zswap, zswap maintains a mapping
of the swap entry, a combination of the swap type and swap offset, to the zpool
