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.
