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