SYNOPSIS

9       int vm_insert_pfn(struct vm_area_struct * vma, unsigned long addr,
10                         unsigned long pfn);
11

ARGUMENTS

13       vma
14           user vma to map to
15
16       addr
17           target user address of this page
18
19       pfn
20           source kernel pfn

DESCRIPTION

23       Similar to vm_inert_page, this allows drivers to insert individual
24       pages they´ve allocated into a user vma. Same comments apply.
25
26       This function should only be called from a vm_ops->fault handler, and
27       in that case the handler should return NULL.
28
29       vma cannot be a COW mapping.
30
31       As this is called only for pages that do not currently exist, we do not
32       need to flush old virtual caches or the TLB.
