drm_vma_node_allow — Add open-file to list of allowed users
int drm_vma_node_allow ( | struct drm_vma_offset_node * node, |
struct file * filp); |
Add filp to the list of allowed open-files for this node. If filp is
already on this list, the ref-count is incremented.
The list of allowed-users is preserved across drm_vma_offset_add and
drm_vma_offset_remove calls. You may even call it if the node is currently
not added to any offset-manager.
You must remove all open-files the same number of times as you added them before destroying the node. Otherwise, you will leak memory.
This is locked against concurrent access internally.
