IIUC, the existing abort_request() codepath only cancels the I/O on the client/gw side. A TMF ABORT successful response should only be sent if we can guarantee that the I/O is terminated at all layers below, so I think this would have to be implemented via an additional OSD epoch barrier or similar.

Hi David,
I was thinking we would get the block request then loop down to all its osd requests and cancel those using the same osd request cancel function.
