*	mm/zpool: use prefixed module loading	Kees Cook	2014-08-30	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	To avoid potential format string expansion via module parameters, do not use the zpool type directly in request_module() without a format string. Additionally, to avoid arbitrary modules being loaded via zpool API (e.g. via the zswap_zpool_type module parameter) add a "zpool-" prefix to the requested module, as well as module aliases for the existing zpool types (zbud and zsmalloc).

*	mm/zpool: implement common zpool api to zbud/zsmalloc	Dan Streetman	2014-08-07	1	-0/+364
	Add zpool api. zpool provides an interface for memory storage, typically of compressed memory. Users can select what backend to use; currently the only implementations are zbud, a low density implementation with up to two compressed pages per storage page, and zsmalloc, a higher density implementation with multiple compressed pages per storage page.
