- * @gtt_size: The size in bytes allocated for the vma in the GTT.

- * @pages_rsgt: The refcounted sg_table holding the reference for @pages if any.
- * @mr: The memory region pointed for the pages bound.
- * @kref: Reference for this structure.
- * @vma_resource: FIXME: A means to keep the unbind fence from signaling.
- * Temporarily while we have only sync unbinds, and still use the vma
- * active, we use that. With async unbinding we need a signaling refcount
- * for the unbind fence.
- * @page_sizes: The vma GTT page sizes information.
- * @onstack: Whether the structure shouldn't be freed on final put.
- * @present: Whether the structure is present and initialized.
