# drm\_mm\_replace\_node(9)

move an allocation from old to new

## NAME

drm\_mm\_replace\_node - move an allocation from *old* to *new*

## SYNOPSIS

**void drm\_mm\_replace\_node(struct drm\_mm\_node \*** *old***, struct drm\_mm\_node \*** *new***);**

## ARGUMENTS

*old*

drm\_mm\_node to remove from the allocator

*new*

drm\_mm\_node which should inherit *old*'s allocation

## DESCRIPTION

This is useful for when drivers embed the drm\_mm\_node structure and hence can't move allocations by reassigning pointers. It's a combination of remove and insert with the guarantee that the allocation start will match.
