* @intr: Whether to lock interruptible.
* @num_shared: Number of dma-fence slots to reserve in the locked objects.
*
* Locks the vm dma-resv objects and all the dma-resv objects of the
- * buffer objects on the vm external object list. The TTM utilities require
- * a list of struct ttm_validate_buffers pointing to the actual buffer
- * objects to lock. Storage for those struct ttm_validate_buffers should
- * be provided in @tv_onstack, and is typically reserved on the stack
- * of the caller. If the size of @tv_onstack isn't sufficient, then
- * storage will be allocated internally using kvmalloc().
+ * buffer objects on the vm external object list using helpers provided
+ * by drm_exec.
*
* The function performs deadlock handling internally, and after a
* successful return the ww locking transaction should be considered
* sealed.
*
- * Return: 0 on success, Negative error code on error. In particular if
- * @intr is set to true, -EINTR or -ERESTARTSYS may be returned. In case
- * of error, any locking performed has been reverted.
