* sleeping (waiting for rendering to finish, say), while you wish to have
* mutual exclusion on an object. For this reason, all drm-related operations
* on drm objects must acquire the DRM_BUSY flag on the object as the first
* thing that they do. If the BUSY flag is already on the object, set DRM_WANTED
* and sleep until the other locker is done with it. When the BUSY flag is
* acquired then only that flag and a reference is required to do most
* operations on the drm_object. The uvm object is still bound by uvm locking
* protocol.
