Zpool is a common frontend for memory storage pool implementations. These pools are typically used to store compressed memory objects, e. g. for Zswap, the lightweight compressed cache for swap pages.
This patch provides the interface to use Zpool in Rust kernel code, thus enabling Rust implementations of Zpool allocators for Zswap.
