CONFIG_ZSMALLOC: Memory allocator for compressed pages

General informations

The Linux kernel configuration item CONFIG_ZSMALLOC has multiple definitions:

Memory allocator for compressed pages found in drivers/staging/zsmalloc/Kconfig

The configuration item CONFIG_ZSMALLOC:

Help text

zsmalloc is a slab-based memory allocator designed to store compressed RAM pages. zsmalloc uses virtual memory mapping in order to reduce fragmentation. However, this results in a non-standard allocator interface where a handle, not a pointer, is returned by an alloc(). This handle must be mapped in order to access the allocated space.
