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.
