DRM_VMA_NODE_REVOKE(9) DRM Core DRM_VMA_NODE_REVOKE(9)

NAME

drm_vma_node_revoke - Remove open-file from list of allowed users

SYNOPSIS

void drm_vma_node_revoke(struct drm_vma_offset_node * node, struct file * filp);

ARGUMENTS

node
Node to modify
filp
Open file to remove

DESCRIPTION

Decrement the ref-count of filp in the list of allowed open-files on node. If the ref-count drops to zero, remove filp from the list. You must call this once for every drm_vma_node_allow on filp.
This is locked against concurrent access internally.
If filp is not on the list, nothing is done.
