19Memory Allocation Controls
20==========================
21
22Functions which need to allocate memory often use GFP flags to express
23how that memory should be allocated. The GFP acronym stands for "get
24free pages", the underlying memory allocation function. Not every GFP
25flag is allowed to every function which may allocate memory. Most
26users will want to use a plain ``GFP_KERNEL``.
