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``.
