- * @shrink: A single callback to shrink TTM memory usage. Extend this
- * to a linked list to be able to handle multiple callbacks when needed.
- * @swap_queue: A workqueue to handle shrinking in low memory situations. We
- * need a separate workqueue since it will spend a lot of time waiting
- * for the GPU, and this will otherwise block other workqueue tasks(?)
- * At this point we use only a single-threaded workqueue.
- * @work: The workqueue callback for the shrink queue.
- * @lock: Lock to protect the @shrink - and the memory accounting members,
- * that is, essentially the whole structure with some exceptions.
- * @zones: Array of pointers to accounting zones.
- * @num_zones: Number of populated entries in the @zones array.
- * @zone_kernel: Pointer to the kernel zone.
- * @zone_highmem: Pointer to the highmem zone if there is one.
- * @zone_dma32: Pointer to the dma32 zone if there is one.
- *
- * Note that this structure is not per device. It should be global for all
- * graphics devices.
