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