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``.
