huge_node

Name:huge_node(@vma, @addr, @gfp_flags, @mpol)*@vma: virtual memory area whose policy is sought*@addr: address in @vma for shared policy lookup and interleave policy*@gfp_flags: for requested zone*@mpol: pointer to mempolicy pointer for reference counted

Proto:int huge_node(struct vm_area_struct *vma, unsigned long addr, gfp_t gfp_flags, struct mempolicy **mpol, nodemask_t **nodemask)

Type:int

Parameter:

Type	Parameter	Name
struct vm_area_struct *	vma
unsigned long	addr
gfp_t	gfp_flags
struct mempolicy **	mpol
nodemask_t **	nodemask

1962

mpol = get_vma_policy(@vma, @addr)*@vma: virtual memory area whose policy is sought*@addr: address in @vma for shared policy lookup* Returns effective policy for a VMA at specified address

1963

* nodemask = NULL

1965

If Value for the false possibility is greater at compile time(See MPOL_* above == MPOL_INTERLEAVE) Then

1966

nid = Determine a node number for interleave

1968

Else

1969

nid = Return the node id preferred by the given mempolicy, or the given id

1970

If See MPOL_* above == MPOL_BIND Then nodemask = interleave/bind

1973

Return nid
