 /**
- * drm_mode_create_dumb_ioctl - create a dumb backing storage buffer
- * @dev: DRM device
- * @data: ioctl data
- * @file_priv: DRM file info
- *
- * This creates a new dumb buffer in the driver's backing storage manager (GEM,
- * TTM or something else entirely) and returns the resulting buffer handle. This
- * handle can then be wrapped up into a framebuffer modeset object.
- *
- * Note that userspace is not allowed to use such objects for render
- * acceleration - drivers must create their own private ioctls for such a use
- * case.
- *
- * Called by the user via ioctl.
- *
- * Returns:
- * Zero on success, negative errno on failure.
