# remap\_vmalloc\_range(9)

map vmalloc pages to userspace

## 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

## RETURN

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)
