From 5acbee4648789ba1fe9e7942280fb1966c76bd6f Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 27 Jun 2016 10:32:02 +0100 Subject: rxrpc: Provide queuing helper functions Provide queueing helper functions so that the queueing of local and connection objects can be fixed later. The issue is that a ref on the object needs to be passed to the work queue, but the act of queueing the object may fail because the object is already queued. Testing the queuedness of an object before hand doesn't work because there can be a race with someone else trying to queue it. What will have to be done is to adjust the refcount depending on the result of the queue operation.
