NAME¶
vm_insert_pfn - insert single pfn into user vmaSYNOPSIS¶
int
vm_insert_pfn(struct vm_area_struct * vma,
unsigned long addr,
unsigned long pfn);
ARGUMENTS¶
vmauser 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.COPYRIGHT¶
