ZswapConfig
ZswapConfig is a zswap (compressed memory) configuration document.
When zswap is enabled, Linux kernel compresses pages that would otherwise be swapped out to disk.
The compressed pages are stored in a memory pool, which is used to avoid writing to disk
when the system is under memory pressure.
