Keep a size limited list with error cookies and flush them in terminate all?

I think so, terminate_all anyway cleans up the channel. Btw what is the
behaviour on error? Do you terminate or somthing else?

On error, I flush all outstanding transactions with an error code and I reset
the channel. After the reset, the DMA channel is functional again. The client
doesn't need to shutdown anything.

You mean from the client context or driver?
