Name
remap_vmalloc_range_partial —
map vmalloc pages to userspace
Synopsis
int remap_vmalloc_range_partial ( | struct vm_area_struct * vma, |
| | unsigned long uaddr, |
| | void * kaddr, |
| | unsigned long size); |
Arguments
vma
vma to cover
uaddr
target user address to start at
kaddr
virtual address of vmalloc kernel memory
size
size of map area
Returns
0 for success, -Exxx on failure
This function checks that kaddr is a valid vmalloc'ed area,
and that it is big enough to cover the range starting at
uaddr in vma. Will return failure if that criteria isn't
met.
