+Memory Allocation Controls
+==========================
+
+Functions which need to allocate memory often use GFP flags to express
+how that memory should be allocated. The GFP acronym stands for "get
+free pages", the underlying memory allocation function. Not every GFP
+flag is allowed to every function which may allocate memory. Most
+users will want to use a plain ``GFP_KERNEL``.
