drm_vma_node_verify_access (9)

int drm_vma_node_verify_access(struct drm_vma_offset_node * node, struct file * filp);

node

Offset node

filp

Open-file

This checks whether filp is granted access to node. It is the same as drm_vma_node_is_allowed but suitable as drop-in helper for TTM verify_access callbacks.

0 if access is granted, -EACCES otherwise.
