- * @size: size of the buffer
+ * @size: size of the buffer; invariant over the lifetime of the buffer.
* @file: file pointer used for sharing buffers across, and for refcounting.
* @attachments: list of dma_buf_attachment that denotes all devices attached,
* protected by dma_resv lock.
* @exp_name: name of the exporter - useful for debugging.
* @owner: pointer to exporter module - used for refcounting kernel module
* @ops: Attach allocator-defined dma buf ops to the new buffer
- * @size: Size of the buffer
+ * @size: Size of the buffer - invariant over the lifetime of the buffer
* @flags: mode flags for the file
* @resv: reservation-object, NULL to allocate default one
* @priv: Attach private data of allocator to this buffer
