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