Name:Allocate pages, preferring the node given as nid. The node must be valid and* online. For more general interface, see alloc_pages_node().

Proto:static inline struct page *__alloc_pages_node(int nid, gfp_t gfp_mask, unsigned int order)

Type:struct page

Parameter:

TypeParameterName
intnid
gfp_tgfp_mask
unsigned intorder
506  VM_BUG_ON(nid < 0 || nid >= MAX_NUMNODES)

509  Return __alloc_pages(gfp_mask, order, nid)
Caller
NameDescribe
__page_cache_alloc
new_non_cma_page
alloc_new_node_pagepage allocation callback for NUMA node migration
alloc_pages_vmaalloc_pages_vma - Allocate a page for a VMA.*@gfp:* %GFP_USER user allocation.* %GFP_KERNEL kernel allocations,* %GFP_HIGHMEM highmem/user allocations,* %GFP_FS allocation should not call back into a file system.* %GFP_ATOMIC don't sleep.
slob_new_pages
kmem_getpagesInterface to system's page allocator. No need to hold the* kmem_cache_node ->list_lock.* If we requested dmaable memory, we will get it. Even if we* did not request dmaable memory, we might get it, but that* would be relatively rare and ignorable.
