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``.
