.SH "NAME"
remap_vmalloc_range \- map vmalloc pages to userspace
.SH "SYNOPSIS"
.HP \w'int\ remap_vmalloc_range('u
.BI "int remap_vmalloc_range(struct\ vm_area_struct\ *\ " "vma" ", void\ *\ " "addr" ", unsigned\ long\ " "pgoff" ");"
.SH "ARGUMENTS"
.PP
\fIvma\fR
.RS 4
vma to cover (map full range of vma)
.RE
.PP
\fIaddr\fR
.RS 4
vmalloc memory
.RE
.PP
\fIpgoff\fR
.RS 4
number of pages into addr before first page to map
.RE
.SH "RETURNS"
.PP
0 for success, \-Exxx on failure
.PP
This function checks that addr is a valid vmalloc\*(Aqed area, and that it is big enough to cover the vma\&. Will return failure if that criteria isn\*(Aqt met\&.
.PP
Similar to
