VM_INSERT_PFN(9)	  Memory Management in Linux	      VM_INSERT_PFN(9)

NAME
       vm_insert_pfn - insert single pfn into user vma

SYNOPSIS
       int vm_insert_pfn(struct vm_area_struct * vma, unsigned long addr,
			 unsigned long pfn);

ARGUMENTS
       vma
	   user vma to map to

       addr
	   target user address of this page

       pfn
	   source kernel pfn

DESCRIPTION
       Similar to vm_inert_page, this allows drivers to insert individual
       pages they´ve allocated into a user vma. Same comments apply.

       This function should only be called from a vm_ops->fault handler, and
       in that case the handler should return NULL.

       vma cannot be a COW mapping.

       As this is called only for pages that do not currently exist, we do not
       need to flush old virtual caches or the TLB.
