From 2c3a5f9abb1dc5efdab8ba9a568b1661c65fd1e3 Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Mon, 1 Mar 2010 16:10:40 -0800 Subject: RDS: Add flag for silent ops. Do atomic op before RDMA Add a flag to the API so users can indicate they want silent operations. This is needed because silent ops cannot be used with USE_ONCE MRs, so we can't just assume silent. Also, change send_xmit to do atomic op before rdma op if both are present, and centralize the hairy logic to determine if we want to attempt silent, or not.
