16  * INDIO_BUFFER_FLAG_FIXED_WATERMARK - Watermark level of the buffer can not be
17  *   configured. It has a fixed value which will be buffer specific.
23  * @store_to:		actually store stuff to the buffer
26  *			the buffer.
27  * @remove_from:	remove scan from buffer. Drivers should calls this to
28  *			remove a scan from a buffer.
30  * @space_available:	returns the amount of bytes available in a buffer
34  * @set_length:		set number of datums in buffer
35  * @enable:             called if the buffer is attached to a device and the
38  * @disable:            called if the buffer is attached to a device and the
40  * @release:		called when the last reference to the buffer is dropped,
41  *			should free all resources allocated by the buffer.
42  * @modes:		Supported operating modes by this buffer type
45  * The purpose of this structure is to make the buffer element
47  * different buffer designs (space efficiency vs speed for example).
49  * It is worth noting that a given buffer implementation may only support a
