# drm\_vma\_node\_revoke(9)

Remove open-file from list of allowed users

## 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.
