.SH "DESCRIPTION"
.PP
Same as
\fBdrm_vma_node_start\fR
but returns the address as a valid offset that can be used for user\-space mappings during
\fBmmap\fR\&. This must not be called on unlinked nodes\&.
.SH "RETURNS"
.PP
Offset of
\fInode\fR
for byte\-based addressing\&. 0 if the node does not have an object allocated\&.
