RDS: Perform unmapping ops in stages
Previously, RDS would wait until the final send WR had completed and then handle cleanup. With silent ops, we do not know if an atomic, rdma, or data op will be last. This patch handles any of these cases by keeping a pointer to the last op in the message in m_last_op. When the TX completion event fires, rds dispatches to per-op-type cleanup functions, and then does whole-message cleanup, if the last op equalled m_last_op. This patch also moves towards having op-specific functions take the op struct, instead of the overall rm struct. rds_ib_connection has a pointer to keep track of a a partially- completed data send operation. This patch changes it from an rds_message pointer to the narrower rm_data_op pointer, and modifies places that use this pointer as needed. Signed-off-by: Andy Grover <andy.grover@oracle.com>
