NAME¶
drm_vma_node_allow - Add open-file to list of allowed usersSYNOPSIS¶
int
drm_vma_node_allow(struct drm_vma_offset_node * node,
struct file * filp);
ARGUMENTS¶
nodeNode 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¶
