that is currently being sent (its a rare race condition, but theoretically possible). The reason is that we repost the inline data buffer for receive before we post the send request. We used to have?? The same buffer is posted at the same time for send and recv? That is never OK, SRQ or not.
We will never POST it for a SEND, but it would be used as the target of RDMA READ / WRITE operations. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
