This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.
