REMAP_VMALLOC_RANGE(9)					    Memory Management in Linux					    REMAP_VMALLOC_RANGE(9)

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)
