NAME

6       remap_vmalloc_range_partial - map vmalloc pages to userspace
7

SYNOPSIS

9       int remap_vmalloc_range_partial(struct vm_area_struct * vma,
10                                       unsigned long uaddr, void * kaddr,
11                                       unsigned long size);
12

ARGUMENTS

14       vma
15           vma to cover
16
17       uaddr
18           target user address to start at
19
20       kaddr
21           virtual address of vmalloc kernel memory
22
23       size
24           size of map area
25

RETURNS

27       0 for success, -Exxx on failure
28
29       This function checks that kaddr is a valid vmalloc´ed area, and that it
30       is big enough to cover the range starting at uaddr in vma. Will return
31       failure if that criteria isn´t met.
32
33       Similar to remap_pfn_range (see mm/memory.c)
