config ZSMALLOC tristate "Memory allocator for compressed pages" # X86 dependency is because of the use of __flush_tlb_one and set_pte # in zsmalloc-main.c. # TODO: convert these to portable functions depends on X86 default n help 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.
