This commit: commit af2b040e470b470bfc881981db3c796072853eae Author: Al Viro <viro@zeniv.linux.org.uk> Date: Thu Nov 27 21:44:24 2014 -0500 Subject: rxrpc: switch rxrpc_send_data() to iov_iter primitives incorrectly changes a do-while loop into a while loop in rxrpc_send_data(). Unfortunately, at least one pass through the loop is required - even if there is no data - so that the packet the closes the send phase can be sent if MSG_MORE is not set.
