Name

remap_vmalloc_range — map vmalloc pages to userspace

Synopsis

int remap_vmalloc_range (struct vm_area_struct * vma,
 void * addr,
 unsigned long pgoff);
 

Arguments

vma

vma to cover (map full range of vma)

addr

vmalloc memory

pgoff

number of pages into addr before first page to map

Returns

0 for success, -Exxx on failure

This function checks that addr is a valid vmalloc'ed area, and that it is big enough to cover the vma. Will return failure if that criteria isn't met.

Similar to remap_pfn_range (see mm/memory.c)
