+Memory Allocation Controls
+==========================
+
+Linux provides a variety of APIs for memory allocation from direct
+calls to page allocator through slab caches and vmalloc to allocators
+of compressed memory. Although these allocators have different
+semantics and are used in different circumstances, they all share the
+GFP (get free page) flags that control behavior of each allocation
+request.
