SYNOPSIS
- int drm_vma_node_allow(struct drm_vma_offset_node * node, struct file * filp);
ARGUMENTS
node
-
- Node to modify
filp
- Open file to add
DESCRIPTION
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.
RETURNS
0 on success, negative error code on internal failure (out-of-mem)
